Zhang Yuan, a "hidden gentleman", wrote about the history of tea with the title of Tea Record. This book * * * is about 17 words, divided into 23 articles, with comprehensive and rich contents, incisive language and many famous sayings, such as "brew tea's main idea, temperature first". "If you sip God alone, two guests will win, three or four will be fun, five or six will be broad, and seven or eight will be giving." "Tea has its own true fragrance, true color and true taste." "Tea is the god of water, and water is the body of tea." Zhang Yuan also has many original ideas. He put forward the idea of "throwing tea in an orderly way, and advocated the method of" throwing it up ","throwing it in the middle "and" throwing it down ",and said that making tea should be" throwing it in the spring and autumn, throwing it in the summer and throwing it in the winter ". On the water for making tea, he dared to put forward a different point of view from his predecessors. He thought that making tea needed a "skillful" soup, that is, boiling it until it was silent, because "the soup had to boil five times", and the water vapor disappeared completely, and Yuan Shen originated.
