普洱茶原料降价或超普洱茶原料降价或超20%

普洱出口有所下跌普洱出口有所下跌 

“几乎整个普洱茶行业的价格都明降或暗降了。”在昨日举行的2008年中国(广州)国际茶业博览会新闻发布会 上,一名广东茶商透露,今年普洱茶原料价格有20%以上的降幅,更有数据显示云南晒青毛茶价格比去年下降50% 以上。 

普洱茶出口有所下跌普洱茶出口有所下跌 在昨日举行的新闻发布会上,广东省茶叶行业协会秘书长张黎明透露了一组数据:“2008年1~9月我国茶叶出口 22.76万吨,同比增长4.97%,只有乌龙茶和普洱茶出口有所下跌,其中乌龙茶下跌2.99%,而普洱茶却下降 33.48%。” 

一名从2004年始进入普洱茶市场、主推古树茶的商家深切体会市场的变化:在2007年,整个市场的茶叶原料被 商家争相哄抬,价格不断上涨,导致普洱茶市场价格的快速上浮;而今年原料起码跌了20%~50%,导致市场价格 也相应下调。在该名商家看来,市场经过1年的沉淀,曾经存在的水分已逐渐被挤干,回到较为踏实的原地。 

不过,行内人士认为,普洱茶市场需要一段为期不短的时日才能恢复昨日风光,主要是高峰期时部分不良炒家破 坏了市场平衡,影响市场信心;另外,负面消息的传播也极大损害了普洱茶的声誉。 

也有观点认为,目前全国茶叶总产量的75%主要依靠内销,市场首先需要调动内需,令消费者重新接受普洱茶, 并对普洱茶有更深的认识;其次要树立正确的普洱茶标准,不将其视同单一的投资品种。(记者 林琳)

Delightful World of Puer Tea
By Brenda Koller
Special to The Korea Time
s

With countless coffee houses springing up everywhere in Seoul, you may be surprised to know that, second to water, tea is the most preferred beverage for the majority of people around the world.

But how often do you think about what type of tea you are drinking, where it was grown, how it was processed and what is the best way to drink it? I pondered those questions and more during a delightful afternoon at the ``World Tea Festival 2007'' held at COEX from June 27 to July 1.

About 200 booths from eight countries including world renowned tea companies exhibited everything you might want to know about tea culture from tea products such as pots and cups, tables, utensils, books, and most importantly, hundreds of different varieties and styles of tea.

Although tea has been popular for over 5,000 years, the market for tea is increasing. According to organizers of the event, sales of tea beverages in Korea have increased by 40 percent over last year with the Korean market valued at 40 billion won. 

Studies have shown that drinking tea has many health benefits such as reducing the risk of cancer and coronary heart disease, to name just two. And with more and more people following the well-being trend, it's no wonder that tea's popularity is on the rise.

All tea originates from the plant Camellia sinensis and there are four basic types _ black, green, oolong or white. The exception to this is puer tea (also spelled puerh, pu-erh, pu erh).

Tea was first discovered in China and the history of puer tea dates back centuries to ancient tea plants that still grow today in Yunnan.

I had the pleasure of discovering puer tea at the World Tea Festival when I sat down at the Jiyumyungcha puer tea store's booth. After the first sip I was enthralled; after the second sip I was hooked. Puer tea looks and tastes similar to black tea, but has a bold aroma and taste of its own, a taste that kept me lingering at the company's booth. 

It certainly helped that one of the company's servers, Jacqueline Park, spoke English and was more than willing to explain the many intricacies of puer tea to a novice drinker.

Park explained that there are two basic kinds of puer, one of China's most popular teas: Sheng Cha, which is raw, naturally fermented puer, and Shu Cha, which is cooked and undergoes an accelerated fermentation process. 

My taste tests revealed a preference for Sheng Cha, which is less woody or earthy tasting than Shu Cha. Puer is also categorized by shape and is available in a variety of shapes such as tea bags, loose-leaf, disc and bowl-shaped, which resembles little acorn-sized bowls.

In many ways, Puer tea can be compared to fine wine as it evolves as it ages and the value often increases with age. Park said that she has tasted puer tea that is much older than herself.

Puer tea purportedly helps with digestion and intestinal activities, not to mention the calming effect it imparts while savoring its unique flavor.

My interest piqued, the quest for additional knowledge of puer tea led me to David Kilburn, chairman of the Tea Museum, who suggested I visit his shop at Lotte Department Store in Myeong-dong. There, manager Choi Eun-sil (who is also fluent in English) introduced me to the company's eight styles of puer tea. Kilburn had suggested sampling two in particular.

Jinhong puer is a blend of puer from Yunnan and cinnamon from Sri Lanka, which is based on a traditional method used by the Jinuo tribes people in China. The blend imparts a delicate cinnamon taste that pleasantly enhances the flavor of the tea.

Of particular interest at the Tea Musuem was the orange puer, which not only tastes delectable but also looks lovely. It is made by removing all the fruit from the inside of a small, bitter orange native to China. 

The tea is then pressed inside the shell and allowed to dry and mature. Choi crumbled part of the orange in with the tea before allowing it to steep. The tea was most pleasant, imparting a refreshing touch of citrus.

I'll admit, I would be hard-pressed to give up my afternoon shot of espresso, but I simply cannot imagine a day without tea. And now my tea drinking has been greatly enhanced with delicious and mysterious puer tea.

Perspectives on Storing and Aging Pu'er Teas: Buying Aged Tea -- But Why?

by WARREN PELTIER

A Brief Historical Perspective

Not so long ago, aged tea could be had for pretty cheap. But all of a sudden, a lot of people in Asia got pu'er crazy, and started buying up all kinds of aged pu'er -- any pu'er -- regardless of quality or price. Let’s take a glimpse at some of the historical highlights of all of this:

Hong Kong has a long history of Pu'er drinking. Pu'er is used here for its medicinal properties, and has long been a favorite tea for consumption during dim sum meals in Hong Kong teahouses.

People’s Republic era: Hong Kong became the “tea storehouse” for pu'er tea. It was sent from Guangzhou to Hong Kong, where some was consumed locally by Hong Kong people, and some was exported to South East Asia.

1950s: one tong of good quality pu'er bing cha cost just a little over 3 HKD. By that time Guangdong people knew that the older pu'er gets, the better it is. But at that time, even old pu'er was only 1 yuan per pound more expensive than newer pu'er. 

1986: One 30-year-old aged Hong Yin (Red Label) bing was selling in Sheung Wan-area tea stores for a little over 170 HKD; some Lao Hao bings aged to 50 or 60 years were selling for 800 HKD. At that time it was already considered very expensive. But today it would be worth in the tens of thousands of HKD.

Starting in the 80s, Hong Kong’s economy started to boom, creating wealth, and a wealthy class of people. Some of these people started collecting pu'er teas as a kind of investment speculation.

In the mid and late 90s, some of the big teahouse owners went overseas -- because of uncertainty about Hong Kong’s future. But after 1997, they came back, started to clean their storehouses, and discovered that there were many kinds of good-quality aged pu'er in their stores. They then proceeded to sell off these stores to collectors in Taiwan and overseas. And two teahouses in particular -- Gam San Lau (金山樓) and Long Moon Lau (龍門樓) (see end-note) -- had stores of Tong Qing Hao Lao Yuan Cha (同慶號老圓茶), aged to almost 100 years in their possession.

Pu'er collectors, especially from Taiwan, would go to the tea farms and factories in Yunnan, sometimes buying up whole crops of tea leaves before they could reach market -- and thus securing their own private stock of tea to be privately pressed into bings for aging.

And that is what kicked off the big pu'er mania -- where everyone who was anyone had to have 100-year-old aged pu'er in their collection. And then supplies of good pu'er, even recently produced, became scarce. Of course, the likelihood of finding 100 year aged pu'er nowadays is virtually impossible.

Value Decisions

Just assume that there were some real, verifiable 100-year-old aged pu'er available for purchase to lucky you. And best of all, that you could actually afford it without going broke. Would that particular brick or bing of pu'er be worth it? That’s the question that has to be asked with any aged tea. Is it worth it to buy this tea? First of all, you probably don’t know the whole history of that tea. Sure, you can research wrappers and factories and batch codes. But that doesn’t tell you anything about how Person A, who first bought the tea, stored it. It doesn’t tell you whether the tea happened to come in contact with any extraneous odors. It doesn’t tell you that Person B stored the tea on a shelf next to a pair of his stinky shoes. It doesn’t tell you that Person C, who then bought the tea, brought it home in a rain storm, and it got all soaked. It doesn’t tell you that Person D doctored the tea by adding extraneous scents from camphor wood to the tea, just because that person thought that the tea smelled kind of like stinky shoes and mold, and thought that it would smell better (and perhaps taste better too) if it were scented with camphor wood.

Since you don’t know the exact storage methods used during the history of that tea, and since you haven’t tasted that tea, how will you know if that tea, aged 100 years is really good or not? You can’t know. And you also won’t know if it’s worth the price you paid. It just may be too big a risk to take.

So how pu'er teas are stored is important, not just for drinking, but also for resale value, if one were to ever be insane enough to sell part of his/her pu'er collection. Of course, pu'er manufacturers know how to age and store tea. And they know how to ship it. So you don’t have to be worried so much how the tea was stored in some warehouse at the factory.

But whether a tea is aged 10 years or 100 years, how the tea was stored is an important factor that will affect the quality of the tea over time. The longer the period of aging, the more important how a tea was stored during all those years becomes. And because of this, one should keep in mind that just because a tea is old doesn’t necessarily mean that it’s good. Of course, Chinese have a saying with pu'er: “the more aged, the better the tea becomes.” But that’s all relatively speaking. If the pu'er was stored improperly, or under non-ideal conditions, then it may be mediocre -- or bad -- aged tea.

In the past few years, in Mainland China, many extremely wealthy people (including many who don’t know a thing about pu'er) got into collecting pu'er as an investment. They speculate in pu'er, driving up the prices -- and driving real pu'er lovers out of the market. There are now many pu'er drinkers who are extremely negative about buying aged pu'er. And they refuse to buy any pu'er until the prices start reflecting the actual value of the tea. 

I myself refuse to buy any aged pu'er, partly because of outrageous prices, and partly because I’m not sure how that particular tea was stored; and also because there are so many fake and forged aged teas that it’s too complicated to keep up with. Now, when I buy pu'er, I visit several reputable dealers where I can sample many relatively new (aged 3 years or less) sheng pu'er bings; and compare prices. If I taste a particular sheng pu'er and I like it now, then when I take it home and store it away for say 7-10 years (or even longer), surely it will taste much better after proper storage and aging. 

Did the Pu'er Bubble Go Bust?

Pu'er prices rose dramatically in the first half of 2007, with prices of mao cha doubling. But this didn’t last long. By the end of June, prices had fallen dramatically as the following examples illustrate:

2007 Price Comparison Prices of Mao Cha

April 1, 2007
Banzhang Ancient Tea Tree: 1400 yuan/Kg
Bulang Shan Ancient Tea Tree: 600 yuan/Kg

July 1, 2007
Banzhang Ancient Tea Tree: 600 yuan/Kg
Bulang Shan Ancient Tea Tree: 300 yuan/Kg

According to market reports, in July 2007, pu'er mao cha prices remained calm, but tea farmers in Nan Nuo Shan (南糯山) and Bu Lang Shan (布朗山) were unwilling to ship their harvests because the going price was so low. And factories in Menghai stopped receiving shipments of tea; many factories reduced the production of shu pu'er. 

So overall, the market was in a bit of a turndown in 2007. No longer were consumers driving the market based on quantity: by the end of the year, they were demanding quality. And that drove prices back down. The demand just wasn’t there anymore.

Today’s Pu'er Market

At the end of June 2008, in Guangdong’s Fang Cun Tea Market, we see pu'er tea prices going down -- sometimes dramatically. A 357-gram 2008 Da Ye 0622 Sheng Bing is selling for 350 yuan per tong. With seven bings in a tong, that comes to 50 yuan per bing. Don’t take my word for it -- see for yourself at this page.

If the prices of pu'er continue to fall, that will be good for consumers. And maybe now is the time to start stocking up on pu'er. A recent trip to the Dong Pu Tea Market, in Fuzhou’s Jin An district, seems to verify suspicions. Tea vendors there say business is slow. Shu bings were selling for a mere 30 yuan. A 400-gram 2007 Meng Ku Large Tea Tree shu bing sold for 80 yuan. And that was the vendor’s asking price. I didn’t even try to bargain him down. If I had bought a tong or two, I probably could have got them for 60 or 70 yuan each. Keep in mind, Dong Pu Tea Market is a backwater tea market with only about 20 vendors. Much larger Pu'er markets, like Guangzhou or Shenzhen, or even Fuzhou’s larger Five-Mile Pavilion Tea Market, probably have stores of sheng bings at a much lower price point. Pre-2007 bings however, and the more famous brands of pu'er are still selling for a relatively high price. As the 2008 bings come onto the market, though, I suspect they will sell for relatively cheaper prices than in the past.

If you want further proof, you can check online auction sites like eachnet.com. The lowest price for a 250-gram 2000 sheng zhuan (brick) was 21.8 yuan. Shu bings are going for as low as 18 yuan. You see similar low prices on online tea vendor sites in China. And that leads to another question: with prices so low, what will the future hold for the new huge tea markets that sprouted up overnight in places like Shenzhen during the days of Pu'er Mania?

Pu'er Reality Check

What makes people go so crazy about pu'er anyway? Is it the moldy smell that people find so captivating or what? What’s all the mystique surrounding pu'er? And why would individual pu'er collectors go out of the way to buy a whole tea farm’s crop and hoard it? Why? Tea Hoarder! That’s tea insanity! And why would anyone be willing to fork over hundreds to thousands of yuan for a single bing? If you compare the quality of leaf in a bing to that of any other kind of tea (say Tieguanyin, for example), are you really getting value for money? For the most part, the pu'er leaf that is used for bings comes from the 4th to the 8th leaves on the bush (or tree). These are pretty large, coarse leaves that are used. Don’t fool yourself: those leaves aren’t big because they come from some thousand-year-old “ancient tea tree.” So why would anyone willingly spend large sums of money for teas that are made with so-called inferior quality leaves? I find it ironic that the teas I buy actually cost as much as, or even more than, the teaware I buy. It’s an expensive lifestyle.

Sensible Enjoyment

So my advice is: Wait awhile and see if cheaper prices make their way through the supply chain. And then, buy pu'er because you like the taste, not because of fame or reputation, or because of the duration of aging. Tea should be enjoyable, not an aggravation. If some of your pu'er tastes good now, then drink it now and enjoy it. Why wait to store it? But if you can wait, then store some away and see what happens. So, enjoy some now, enjoy some later. Maybe that’s the best way to buy and store pu'er.

Why YIWU : A Puer Tea Home

By Kathy Zhang (Jinghong Zhang)
Resource Management in Asia-Pacific Program,
Research School of Pacific & Asian Studies, The
Australian National University


I have now visited Yiwu, the small township (xiang) in Yunnan province of China where Puer tea is produced, twice. The first occasion was in November of 2002, when I happened to be there with a film crew, but I was there for only one day. The other time was in February of 2006, when I was able to be there for a week, and I had a clearer aim in mind, since I was undertaking a preliminary visit for my planned Ph.D. project on Puer tea. Although both were short stays, I found Yiwu an interesting place and a good site for further research. 

In February I took the bus from Jinghong, the capital city of Xishuangbanna Dai Autonomous Prefecture, in Yunnan Province of southwest China. It took me about four hours travelling southeastwards to get to Yiwu, one of the towns in Mengla 
County (xian) of Xishuangbanna. 

Going on the memory of my last visit, I turned off at the middle of the main street and got to the so-called “old street”, which is more rural in appearance. Old family houses line the street, with farmland in between them and shrub tea plantations in 
the surrounding hills. There are more wild tea trees in the more distant villages of Yiwu, places which are inhabited by a variety of ethnic groups – the Han, the Dai, the Yi, the Yao, and the Bulang. 

What is special about the old street in Yiwu is the architecture, which is all in typical Han vernacular style, although Yiwu is in Xishuangbanna, a place famous for its diverse minority ethnic groups. From the mid 17th century, a group of Han immigrants from Shiping came to Yiwu. Shiping is a county in the southeast 
of Yunnan, and the people there are mostly Han. The original minority groups in Yiwu were the Yi, Bulang and Dai, who made use of wild tea trees, but it was not until after the immigration of the Han that the Yiwu tea trade became famous. 

Instead of the curious looking up and down that a sudden visitor from the outside might be expected to invite, the locals here usually give me a friendly smile and ask me into their homes to chat. And soon after entering a family’s home, I get to know its particular history. Almost every building along the old street has been famous as a trading post for Puer tea, especially during the late 18th and early 19th centuries. The landlord may have changed, but stories of how the first landlord diligently and cleverly ran and boosted the tea business are still told. 

In 2002, in a clean and comfortable courtyard, I first learned from Zhang Yi, the retired township head, how a brick of Puer tea was made in the traditional way by hand. Also from him, I got to know the fame of the “Six Great Tea Mountains”, located in southeast Xishuangbanna, famed for their ancient wild tea trees. Yiwu is one of these tea mountains and is famous for having been a ‘tribute’ tea area for 163 years (1732-1904) (Zhang Yi 2006: 71), when tea was presented to the Imperial court. Owing to the political climate, the tea industry of Yiwu was halted from time to time, especially during World War II and after 1953 (Zhang Yi 2006: 76-77). Zhang Yi was the one who took the lead in reviving the hand-worked Puer brick again in Yiwu in the mid-1980s, and his success encouraged the other locals to do the same. 

Most families here are in the tea business. Unlike the situation in many counties of China where young people leave to find better opportunities outside, the rise in the demand and price of Puer tea in recent years has encouraged local youths here to stay at home and join the tea industry. After a short break during the Spring Festival, people begin the first picking of the year in late February or early March. The process is divided into several phases and different production units. One family I visited this February has relatives living in another village where the wild tea trees grow, 30 kilometers from Yiwu. Their relatives in the country undertake the task of picking the leaves and deactivating the enzymes through oxidisation. Then the tea leaves are taken by van to the town family, who press the tea leaves into tea-bricks, package, and sell it. The proceeds are then distributed equally between the two families. If business is not done through family connections, the town people usually have some instituted relationship with a certain group of village people and assign the work to them in a similar way. 

Yiwu is not the only place producing Puer tea. Other areas of Yunnan such as Simao, Menghai, Lancang, and Lincang are also famous for it and have ancient wild tea trees, too. The name of ‘Puer’ itself comes from a place in Simao, which used to be an important point of goods collection for taxation purposes. Moreover, ‘Puer’ tea does not necessarily refer to any particular category or species of tea tree. All kinds of tea can be made into Puer tea, after the particular post-fermentation process which distinguishes Puer tea is applied. But the large-leaved variety of tea 
in Yunnan is acknowledged to be the most suited to this process of post-fermentation. 

Puer tea can be further divided into two kinds, according to different methods of post-fermentation. One is ‘raw Puer’, in which post-fermentation is done via natural exposure to the air for a time, without anything else being done. The other is ‘ripe Puer’, where post-fermentation is accomplished in a shorter time by artificial means. Both raw and ripe Puer tea can be kept for a long time, unlike green tea. And the belief that the older Puer is, the better it is, is now becoming popular, which has made a lot of people buy and store Puer tea as a kind of antique. 

Something has happened to Puer tea in the past twenty years. During the 1985 Technological Exposition in Kunming, nobody showed any interest in Zhang Yi’s Puer tea. In the early 1990s, the price of Puer tea before production in Yiwu was ¥5 (US$1 = ¥8) per kilogram; then it was ¥15; then ¥25; in 2005, it reached ¥60 as the basic price, and sometimes even ¥80 or ¥100 per kilogram, with a local family’s annual income reaching ¥50,000 - pretty good for these local farmers. Mostly such income is earned from just picking or processing tea leaves, but other related industries such as tea packaging, porterage, ‘tea culture’ performances, and so on, have been boosted too. A brick of Puer tea sold at ¥50 in Yiwu will be three or five times more expensive in Kunming, Beijing, Hongkong or Taiwan. And its price will definitely increase a lot after being stored for over five years. 

In 2005, a traditional-style caravan of horses organized by some private tea companies of Yunnan started out from Puer to travel overland to Beijing, duplicating the route followed when Puer tea was carried to Beijing as a tribute during the Qing dynasty (1644- 1911). When they finally arrived in Beijing, after more than half a year’s travel, a brick of Puer tea fetched ¥1000 at auction, almost 20 times as much as those sold in the original place. And in April of 2006, another caravan carrying Puer tea was organized by the local government of Yunnan. This time, Yiwu was selected as the starting point, and the destination is hoped and expected to be Taiwan. 

These caravan routes are called the “Ancient Routes of Tea and Horses”. These routes came into being more than two thousand years ago because of the trading and transporting of tea by caravan between southwest China and southeast Asian countries, and were first named in this way by Mu Jihong and another five young scholars after a 90-day investigation on foot in 1989. There are countless ‘Tea-Horse routes’ between Yunnan and outside, and Yiwu is one of the most important starting points, since wild tea trees grow there. Some stories are being now popularized which tell how Puer tea first became naturally fermented during the long travels when it was carried by caravan. Whether these stories are truth or myth, researchers, traders, government leaders and even consumers enjoy chewing on them very much since they seem to prove that Puer tea is really some kind of treasure. Of course, apart from the caravan spectacle mentioned above, most Puer teas at present are carried by means of modern transportation. Along with further research on the ‘Ancient Routes of Tea and Horses’ and the local government’s effort to develop Yunnan as a ‘Tourism and Cultural Province’, Puer tea is getting another chance to boom. 

And Puer tea is becoming a popular and fashionable drink in big cities around China, in some ways even more popular than Longjing or Wulong, which should be drunk when fresh and can’t be kept too long. Both in Beijing and Kunming I heard sayings like: those who don’t drink Puer tea are considered as of little culture; those who drink tea but don’t drink Puer “have no deep sense of tea”. Even those who actually do not like Puer are trying to get used to it. And almost everyone will ask the tea seller one question before actually buying any: “how old is this brick of Puer?” Age usually decides prices, so this can be a hard question for a middleman trader to answer. In Yiwu I got to know that the outside traders usually specify some requests when they pre-order the packing of a piece of Puer brick. First, the weight of a piece or a tube of Puer brick (a tube includes seven pieces) should be marked exactly; second, the product should be made of good quality tea leaves but the tea origin is actually decided pretty much by the traders during the later process of packing; third, no definite date of tea production should be marked on the package, since this only needs to be known and checked during their personal meeting. 

Faced with hot competition between producers, and a variety of different tastes among consumers, it’s hard to say which place produces the best Puer tea. And although post-fermentation is the common process constituting Puer tea, varying geographical conditions and trivial differences of production can lead to diverse tastes of the tea. But for the Puer tea of Yiwu, there are some conspicuous points about its traditional production: 

1. Instead of large-scale enterprises, people adhere to small-scale family businesses which remain the primary unit of tea production;
 
2. People prefer to make raw rather than ripe Puer; 

3. Production by hand is preferred to mechanised production. 

But meanwhile, these traditions are being challenged. In February of 2006, I got to know that a new policy established by the local government is putting pressure on Yiwunese to change their traditional methods. In order to make all Puer tea products in Yiwu conform to a certain agreed standard, the policy prescribes that each unit in the Puer tea industry should be of a certain scale, mainly referring to the size of production; those businesses producing on too small a household scale should close down. As I observed, a lot of families were working hard to extend their processing spaces before the deadline, either within their present houses or by building an additional room outside not far away. But actually this policy is objected to by a lot of locals, since many of them do not have enough money for extension at the moment, or they think the extension might destroy the original architecture, which is an important signs of Yiwu’s identity. For example, Zhang Yi, the pioneer of Yiwu’s Puer tea, said that it is not really necessary for a unit to reach a big scale, as long as it reaches an adequate standard of cleanliness. 

From Zhang Yi’s viewpoint, Puer tea in Yiwu as well as in other places in Yunnan is facing some other problems. First, Yiwu has both tea trees and shrubs. The former are grown naturally on old plantations and have a stronger taste. The latter were developed by people later and are much shorter and younger than the former, but can grow much more quickly. In recent years, the former in Yiwu has an annual production of 70 tonnes; the latter 250 tonnes. However, the annual figure appearing in the market labeled Yiwu is no less than 3000 tonnes, and most are marked as ‘from trees’, which cannot easily be verified by a common consumer. Where do those surplus teas come from? It is really questionable. Secondly, the over-use of pesticide in tea shrub planting is a common problem on many tea plantations. Even if it is true that “the older the better”, what is the point of storing for ages a raw brick which might have come from a plantation where pesticides have been over-used? And how can Puer tea enter the world market successfully? Thirdly, people are so deeply involved in making profits out of Puer tea that with the proliferation of various artful processes it is becoming very difficult not only for consumers or second-hand buyers to tell the exact age of the tea, but also hard for a tea producer to distinguish if the tea leaves he gets from villages are from shrubs or trees. 

The three preferences mentioned above characterise tea production in Yiwu and will form the basis of my further research, through which the voices of the locals versus voices from outside about Puer tea can be examined. Meanwhile, the new challenges facing Yiwu should be examined to see how they will influence future production in this area.
