The origin of drinking 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.

There are different opinions about the origin of tea drinking in China: tracing back to the origin of tea drinking in China, some people think it originated in ancient times, others think it originated in Zhou Dynasty, Qin and Han Dynasties, Three Kingdoms, Southern and Northern Dynasties and Tang Dynasty. The main reason for the disagreement is that there were no tea characters before the Tang Dynasty, but only tea characters were recorded. It was not until Lu Yu, the author of the Book of Tea, restored the word tea and wrote it as tea that it was said that tea originated in the Tang Dynasty. Others are said to have originated in Shennong and Qin and Han Dynasties.
