Black and thin, with a moustache, glasses and a stack of books, it is said that the clothes are too vague, and sometimes I forget to tie a bow tie: Who is this sentence about?

1. Mr. Fujino, the mentor of Mr. Lu Xun!

2. Lu Xun wrote in "From Baicao Garden to San Tan Yin Yue" that San Tan Yin Yue is the master and his teacher. As far as I know, the article did not mention her husband's name, but mentioned that he was a very decent man and a profound scholar. It may also be his teacher, Mr. Shou Jason Wu.

3. Mrs. Yan in "Morning Flowers Pick Up in the Evening".
