Pu’er or Pu-erh Tea(普洱茶)

Pu-erh or Pu'er is a variety of fermented and aged dark tea produced in Yunnan province, China. Fermentation in the context of tea production involves microbial fermentation and oxidation of the tea leaves, after they have been dried and rolled. This process is a Chinese specialty and produces tea known as Hei Cha (黑茶), commonly translated as dark, or black tea (this type of tea is different from what in the West is known as "black tea", which in China is called "red tea" 红茶). The best known variety of this category of tea is Pu-erh from Yunnan Province, named after the trading post for dark tea during imperial China.

Pu'er traditionally begins as a raw product known as "rough" Mao Cha (毛茶) and can be sold in this form or pressed into a number of shapes and sold as "raw" Sheng Cha (生茶). Both of these forms then undergo the complex process of gradual fermentation and maturation with time. The Wo Dui fermentation process (渥堆) developed in 1973 by the Kunming Tea Factory :206 created a new type of pu-erh tea. This process involves an accelerated fermentation into "ripe" Shu Cha (熟茶) which is then stored loose or pressed into various shapes. The fermentation process was adopted at the Menghai Tea Factory shortly after and technically developed there. The legitimacy of shu cha is disputed by some traditionalists in contrast to aged teas. All types of pu-erh can be stored to mature before consumption, which is why it is commonly labelled with year and region of production.

Hani Ethnic Group Clothes(哈尼服饰)

The traditional clothing of the Hani is made with dark blue fabric. The men dress in short jackets and in long wide pants. They also wear white or black turbans. The women dress depends on which clan they belong to. There is no gender difference in the clothing of children under the age of seven.

Ning’er Coffee(宁洱咖啡)

When you hear “China” and “coffee” mentioned in the same sentence, it is usually regarding the booming coffee market in the traditionally tea-drinking country. Less well-known is the fact that coffee is actually grown in China. It is predominantly low-quality arabica used in instant coffee, grown in full sun using high chemical inputs, and the Chinese government is aggressively promoting the expansion of thousands of hectares of coffee production.

Coffee has been grown in Yunnan since the late 1800s, but on a relatively small scale. There was a resurgence in the late 1960s, but today’s Chinese coffee revival was orchestrated in the 1980s by the Chinese government, the United Nations, and at least one large multinational roaster. Very high import tariffs combined with millions of potential new coffee consuming customers has prompted roasters to source coffee from within the country.

Sweet Potato(红薯/黄心山药)

The sweet potato (Ipomoea batatas) is a dicotyledonous plant that belongs to the family Convolvulaceae. Its large, starchy, sweet-tasting, tuberous roots are a root vegetable. The young leaves and shoots are sometimes eaten as greens. Ipomoea batatas is native to the tropical regions in the Americas. Of the approximately 50 genera and more than 1,000 species of Convolvulaceae, I. batatas is the only crop plant of major importance—some others are used locally (e.g. I. aquatica (kangkong)), but many are poisonous. The sweet potato is only distantly related to the potato (Solanum tuberosum) and does not belong to the nightshade family. The genus Ipomoea that contains the sweet potato also includes several garden flowers called morning glories, though that term is not usually extended to Ipomoea batatas. Some cultivars of Ipomoea batatas are grown as ornamental plants; the name tuberous morning glory may be used in a horticultural context.

The plant is a herbaceous perennial vine, bearing alternate heart-shaped or palmately lobed leaves and medium-sized sympetalous flowers. The edible tuberous root is long and tapered, with a smooth skin whose color ranges between yellow, orange, red, brown, purple, and beige. Its flesh ranges from beige through white, red, pink, violet, yellow, orange, and purple. Sweet potato varieties with white or pale yellow flesh are less sweet and moist than those with red, pink or orange flesh.
