Zhang Yuan composed the outstanding "Tea Records" according what he learnt from his long term experience of tea tasting. Xu Cishu was particularly good at tea ceremony and wrote "Tea Reports"; among which Zhu Quan and his "Tea Manual" had a especially important contribution.
  
Zhu Quan (A.D.1378-1448), the seventeenth son of Emperor Zhu Yuanzhang, was considered to have "handsome manner, wisdom and eloquence ". He hid his light and dwelled in seclusion in the South for a long time to live out his life in retirement, during which time he kept his mind clear and calm by tasting tea, playing musical instruments and reading, paying no attention the world affairs. He clearly indicated that his fondness of tea was to use tea as a medium to express his lofty aspirations and to cultivate his moral character rather than to love the taste of tea itself.

Zhu Quan explored the loose tea drinking method after the ball tea processing was stopped. He reformed the traditional drinking method and the tea sets, and advocated simple process to keep the nature of tea.
