Tunxi Green Tea, known as "Green Gold", is famous for its "green leaves, clear soup, mellow fragrance and rich taste". "Tunxi Green" is mainly distributed in ancient Huizhou, because most of the tea merchants from Xiu, She and Wu were concentrated in Tunxi to open tea shops at that time, and the raw tea was concentrated in Tunxi for refinement and shipped to Shanghai from Xin'an River for export abroad, so it was called "Tunxi Green Tea", or "Tunxi Green" for short. The production of Tunxi Green can be divided into 37 processes, with hundreds of variations, and it takes 14 days to be made. It is a typical representative of traditional Chinese handicrafts, which is difficult to be replaced by modern technology and is an extremely important historical and cultural heritage. In the late Qing Dynasty and the early Republic of China, the "Tunxi Green" craftsmanship was the best in the country's green tea. Tea workers must master the principle of "making good tea roughly and making rough tea finely" and configure a tight door screen (a head screen with material specifications) to achieve "no bending and no loss of materials". The process is unique, mainly manifested in: 1. The water content of Tunlu tea is low, and the manual refining adopts raw tea, so the soup color is clear; 2. Tunlu tea is refined by low temperature and long fire, and the tea is repeatedly fired, so the aroma is strong and lasting; 3. Tunlu has many and fine refining processes, so the levels are clear and the strips are uniform. In addition, the raw tea of Tunlu is picked in batches, and the fire used in the initial processing is appropriate, so the color is silver-green and frosty, fresh and tight; 4. Tunlu tea is rolled for a long time, and the cell destruction rate of tea leaves is as high as 75%. Coupled with the unique natural climate, Tunlu is rich in content, thick in taste, and resistant to brewing. The taste does not decrease after three to five brewings. In the 1970s, my country's green tea represented by Tunlu was exported to more than 80 countries and regions on five continents in the world. In 1981, the special first-grade tea produced by Tunxi Tea Factory won the national silver award for high-quality products. In 1985, the special first-grade and the first-grade Zhenmei won the national silver award, and the Gongxi first-grade won the Ministry of Industry's quality award. In 1988, the "Zhongcha Brand" special grade one Zhenmei produced by Tunxi Tea Factory participated in the selection of famous, special, excellent and new products at the first China Food Expo and won the gold medal. In September of the same year, at the 27th World Quality Food Selection Conference held in Athens, the "Tunlu" special grade and special grade one won the silver medal.
