The original author of Seven Categories of Sencha is other than Xu and Lu.
However, if it is "Lu Tong", the content of the "Seven Categories" is not credible; if it is "Lu Shusheng", according to Xu Wei, its "Seven Categories" are redundant works, and It is collated with the "Seven Categories" in Lu's "Cha Lao Ji", and Xu's writing is more complex than Lu's. Therefore, the original author of "Seven Categories of Sencha" may be other than Xu and Lu.
Seven Categories of Sencha Tea" was written around 1575. The main publications are: ①Shuo Yong's continued edition; ②A must-have edition for home use; ③Xu Wenchang's lost herbal medicine.
The whole book is about 250 words, divided into seven parts: character, tasting springs, fried dumplings, tasting tea, tea preparation (the original work of "Xu Wenchang Lost Cao" is "Tea Yi"), tea lovers, tea honors, and The "Seven Categories of Sencha" in Lu Shusheng's "Cha Liao Ji" are the same. Therefore, Wan Guoding said: "It may be that "Shuo Yong Xu" mistitled it."
According to the "Seven Categories of Sencha", there are also running scripts and stone inscriptions passed down from generation to generation (see "Tianxianglou Collection of Notes"), among which are Xu's own postscript says: "The 'Seven Categories' was written by Lu Tong, and...it was slightly modified." There is also a note in the "Xu Wenchang Lost Cao" edition: "The old version of tea is similar to redundant, and it is slightly modified." So we know it. The original author is not Xu Wei.
Xu Wei's calligraphy is mostly done in running and cursive scripts. In addition to learning from the famous masters of the Jin and Tang Dynasties, he mainly absorbed the charm of Mi Fu, Huang Tingjian and Ni Zan of the Yuan Dynasty, thus showing his own artistic character. , most of his handed down works were written after the age of 56.
