Tea belongs to Theaceae, which is an evergreen shrub or small arbor plant with a plant height of 1-6 meters. Tea tree likes humid climate and is widely cultivated in the south of the Yangtze River basin in China. Tea leaves are made into tea leaves and used after soaking in water, which has the effect of strengthening the heart and diuresis. Tea can be picked after three years of planting. Generally, 4-5 leaves of buds are picked before and after Tomb-Sweeping Day, and the quality of tea made from these buds is very good, which belongs to the treasures of tea.
China has a long history of drinking tea, and the exact time cannot be verified, but there is a general statement about the time. We can also find evidence that the habit of drinking tea in many parts of the world was handed down from China. Therefore, many people think that drinking tea was initiated by China people, and the habit of drinking and growing tea in other parts of the world was passed down directly or indirectly from China. However, some people can find evidence that the habit of drinking tea was invented not only in China, but also in other parts of the world, such as India and Africa. 1823, a major of the British invading army discovered wild tea trees in India, and some people began to believe that tea originated in India. Of course, there are records of wild tea trees in China, all of which are concentrated in the southwest, and some areas in Gansu and Hunan are also recorded. Tea tree is a very old dicotyledonous plant, which is closely related to people's lives.
In China, there are also arguments about the earliest origin of tea trees, and there are several opinions. Many people believe that in Yunnan, after careful study, a scholar asserted that Xishuangbanna, Yunnan Province is the origin of tea trees. The earliest written records of artificially cultivated tea trees began with Mengshan tea in the Western Han Dynasty. This is recorded in Sichuan Tongzhi.

The processing of Qi Long bubble is to take fresh tea without any fermentation treatment, and kill the tea immediately after entering the factory (killing enzyme activity, so that the chemical components of tea are no longer oxidized), thus retaining the original style of fresh tea.
Qilong foam is rich in amino acids and vitamin C. The higher the amino acid content, the better the quality, which has been clearly confirmed. The content of vitamin C can be used as an indirect index of Qilong foam quality. The quality characteristics of Qilong tea are fresh and natural, loyal to the original flavor, and the tea soup must be sweet and refreshing, with a faint scent of grass or cooked chestnut. Because Qilong tea is rich in amino acids, the tea soup is much sweeter than other teas, and most of the ingredients have maintained their original style without oxidation, so green tea presents the typical characteristics of "soup green, leaf green, fresh and natural". How to describe the quality characteristics of Qilong Bubble? Only one sentence is pure and natural, loyal to the original flavor, just like a clean and flawless "naive child." Drinking dragon bubble with gas has an aura of returning to nature and being calm and comfortable, which is also the reason why Japanese people especially like frying tea, and it also derives the profound artistic conception of "harmony, respect, purity and silence" in Japanese tea ceremony. If you are interested in drinking Qilongpao, you should gradually realize the profound and natural artistic conception. Qi Long bubble is a semi-spherical packaged tea in some fermented teas, which is currently in this province. Qilong's bubble is like a naive child with no experience at all, so it retains the most primitive, freshest and purest flavor, presents a pure and unrestrained atmosphere, and its fermentation degree reaches about 30%, so it presents a more mature, refined and artificial flavor.
Therefore, the price of packaged tea made by Qi Long bubble varieties is usually more expensive, followed by Jin Xuan or Emerald, and the fourth is Four Seasons Spring. In short, if you go to a tea area or a tea shop or teahouse to buy tea, remember that Jinxuan tea has a natural milky fragrance, while Emerald tea has an obvious wild fragrance. The fragrance of Four Seasons Spring is strong, but the taste is a bit bitter, while Qingxin Qilong is a kind of tea with mellow taste, strong aroma, high quality and high price.

(2) Drinking tea can prevent tooth decay.
Drinking tea or brushing your teeth with tea can not only eliminate bad breath, but also prevent dental caries. It is reported that Dacheng Zhou, M.D. of Beijing Stomatological Hospital, has been studying the efficacy of tea in preventing dental caries since 1970s, such as drinking tea, gargling with tea soup, brushing teeth, or using toothpaste containing tea, but brushing teeth with tea soup is the best. This is because tea contains fluorine, which has great affinity with calcium in teeth and can become a kind of "neon apatite" which is difficult to dissolve in acid. Just like adding a protective layer to teeth, it improves the ability of teeth to prevent acid and caries. Using tea to prevent caries is one of the ways to protect teeth. Therefore, gargling, brushing teeth and drinking tea with tea soup can be popularized among children. In low fluorine areas, it is recommended to drink ordinary low-grade tea (high-grade tea and famous tea have low fluorine content) to prevent dental caries. Drinking tea soup brewed with10g of tea every day can meet the human body's demand for fluorine. Tea with high fluorine content includes Fujian oolong tea, Yunnan tea, Yunnan black tea, Zhejiang tea, Jiangxi jasmine tea and Guizhou brick tea.
