Tea according to the degree of fermentation and processing technology can be divided into six categories: green tea, black tea, black tea, oolong tea, yellow tea, white tea.
Green tea: that is, unfermented tea, the fresh leaves are spread out to dry and then directly into the one or two hundred degrees of hot pan frying to maintain its green characteristics.

According to the different methods of drying during processing, green tea can be divided into fried green tea, baked green tea, steamed green tea and sun-clean green tea.
2. black tea: black tea is a fully fermented tea (fermentation degree greater than 80%).
The famous varieties are: Qi Hong, Dian Hong, Ying Hong.
The difference between black tea and green tea lies in the different processing methods. Black tea processing without killing, and withering, so that the fresh leaves lose cloud part of the water, and then kneading, and then fermentation, so that the polyphenols contained in the oxidation of tea, into red compounds. This compound is partly soluble in water, partly insoluble in water, and accumulated in the leaves, thus forming red soup, red leaves. Black tea mainly has three major types of small seed black tea, work black tea and black broken tea.
3. black tea: black tea raw materials, coarse and old, processing pile fermentation time is longer, so that the leaf color is dark brown, so named black tea.
Pu'er tea from Yunnan is one of the black teas. Pu-erh tea is made by pouring water on green tea that has already been made and then fermented. Pu-erh tea is popular in Southeast Asia and Japan for its lipid-lowering, weight-loss and blood pressure-lowering effects. But to really talk about weight loss, the most significant effect is still oolong tea.
4. Oolong tea: Oolong tea, also known as green tea, is a class of semi-fermented tea between black and green tea.

Famous varieties include: Wuyi Rock Tea, Iron Goddess of Mercy, Phoenix Monoceros, and Taiwan Oolong Tea.
Oolong tea is a semi-fermented tea, that is, the production of appropriate fermentation, so that the leaves are slightly red, is between green tea and black tea, a type of tea. It has the freshness of green tea and the sweetness of black tea. Because the middle of the leaf is green, the edge of the leaf is red, so there is a "green leaf red edging" said.
5. Yellow tea: yellow tea in the tea-making process, after the smothering pile of yellow, resulting in the formation of yellow leaves, yellow soup.
The famous Junshan silver needle tea belongs to the yellow tea, yellow tea production method is a bit like green tea, but the middle needs to be smothered for three days.
Yellow tea can be divided into "yellow bud tea" (including Hunan Dongting Lake Junshan silver buds, Sichuan Ya'an, Mengding yellow buds of the county, Anhui Huoshan Huonei buds), "yellow small tea" (including Hunan Yueyang Beigang in, Hunan Ningxiang Weishan Mao Jian, Pingyang, Zhejiang Pingyang yellow soup, Hubei Yuanan's Luyuan), "yellow big tea" (including the big leaf green, Anhui Huoshan yellow tea) three categories.
6. White tea: white tea is basically made by sunlight. The appearance, aroma and flavor of white and yellow tea are very good.
Famous varieties include: white ho silver needle tea, white peony tea .
White tea is processed without frying or kneading, and only the tender, velvety leaves are dried in the sun or over a gentle fire, leaving the white velvet intact.
