Many people in history were born in poverty or misery. For example, there was such a saint in the Tang Dynasty, that is, Lu Yu, who was known as the "Cha Sheng" among the descendants. His birth was very miserable, which was also reflected in his later self-evaluation. He was an abandoned baby. However, even if he was an abandoned baby, it did not hinder his achievements. With his efforts the day after tomorrow, he finally became a generation of "Cha Sheng".
In folklore, there is a wonderful story about Lu Yu from abandonment to adoption. It is said that on an early morning in late autumn, a Zen master passed by a small stone bridge in the suburbs, and suddenly heard the cries of wild geese under the bridge, so he took a closer look and saw a baby boy under the wild geese, so he took him back to the temple for adoption. Later, he was named as a divination, and the divination words said? ：? "Hung-chien was born on land, and his feathers can be used as instruments", so he was named Lu Yu. Ji Gong can be said to be the guide and the first teacher of Lu Yu's tea art road.
After growing up, Lu Yu loves tea ceremony very much, and gradually seeks her own inner tea ceremony. Young Lu Yu followed the refugees' investigation, gradually collected a large number of first-hand information on tea production and tea making, and accumulated rich experience in tasting spring water and writing some works. Emperor Daizong once gave him a high official, but after politely decline, Lu Yu devoted himself to writing the Tea Classic, which is also the first professional tea monograph in the world.
In this book, the experience of tea harvesting, production and drinking at that time was systematically summarized for the first time, and the issues related to the origin, production and drinking of tea were comprehensively and accurately summarized, which spread the scientific knowledge about tea and promoted the production and development of tea to a certain extent. And Lu Yu was finally regarded as Cha Sheng by later generations by virtue of the book Tea Classic, and was respected and admired by people who love tea in later generations.
