The reason for this is that the national strength of the Tang Dynasty at that time was strong, which led to a great demand for tea among the people in society. At the same time, tea was very popular in Chang 'an at that time, and others in many places began to follow suit, which led to the popularity of tea in the whole country. It is precisely because of this cultural phenomenon in the Tang Dynasty that many neighboring countries also produced a large amount of tea. For example, the Japanese sent a large number of envoys to visit the Tang Dynasty and brought tea back to China when they returned. They followed suit. This way of drinking tea in the Tang Dynasty took tea as its own drink and formed a unique culture, that is, tea ceremony culture.

Tea is something that has existed in China since ancient times. China is the origin of tea, and there is no one. Tea is produced in the southwest of China, mainly in Sichuan and Guizhou, because these places have humid climate, which is very suitable for the growth of camellia. But tea picking is very particular, and they also have different names for tea picked at different times. For example, the tea picked before Tomb-Sweeping Day is called Qianming Tea, which is a very precious tea in ancient China. Because the yield is very small, and the theanine and tea polyphenols contained in tea are very rich, people will have a strong aromatic taste when drinking it.

In the Tang Dynasty, Shandong people began to soak water with tea. People find that these teas are used for soaking water and have a unique taste, so local people regard tea as their own drink. Over time, this practice spread to Chang 'an at that time. Chang 'an, as the capital of the Tang Dynasty, had a great influence, so in the streets and alleys of the Tang Dynasty, a kind of drinking tea was formed, which accumulated over time.

To sum up, tea, as a native plant in China, can take root and grow in China because of its unique charm and the development of ancient China dynasties. Besides, Shennong has tasted all the ancient herbs in China. In the process of tasting herbs, Shennong detoxifies with tea, so tea is not only a drink, but also a useful medicinal material, which is very precious.
