Nowadays, drinking black tea is popular in the world, which is also left by China's ancestors. At that time, our ancestors used good tea to make green tea and bad leaves to make black tea for foreigners. As a result, foreigners only recognize black tea but not green tea. After the establishment of the British East India Tea Company, the processing technology has been continuously improved, and it has a history of 1000 years. The route of transmission is land and sea; The spreading direction is east, west, north and south, spreading to Central Asia, West Asia to Europe/North to Mongolia, Russia/South to South Asia/East to Korea, Japan and the United States. People like tea more and more, and it has become one of the three major drinks in the world today, which shows how well tea develops. Legend has it that in the era of Three Emperors and Five Emperors, Shennong (about between Fuxi and Huangdi) went up the mountain to collect herbs, and our ancestors tasted them while collecting them that day.

China's tea was introduced into Turkey as early as the 7th century, and soon after the Tang and Song Dynasties, the tea culture radiated outward, forming the Asian tea culture circle. As for European and American countries, it was not until the 7th century that they began to drink tea on a large scale and trade with China. During the period of Emperor Wu of the Han Dynasty, tea was introduced into West Asia and even Europe along the Silk Road as a commodity. Until the westerners colonized and the end of World War II, the ancient Silk Road was silent for hundreds of years. Tea originated in China, and it was first offered as a sacrifice. However, it began to be used as a dish in the late Spring and Autumn Period, developed into medicine in the middle of the Western Han Dynasty, and developed into a high-grade palace drink in the late Western Han Dynasty.

Its production process is mainly through high-temperature deactivation, setting or rolling drying. There are several different ways to deactivate green tea, such as steaming, frying and baking. Cuilan Yuexi is a famous specialty tea in our hometown, which is a typical green tea. I am an old tea farmer, but I also know the hardships of tea farmers. It's hard from picking tea to frying tea. Now it is machine-fried tea. Although the taste is not as good as that of manual cooking, it is also a sign of progress and an inevitable result of social development through picking, drying, processing and packaging.
