The scavenger of the spiritual world-Wei Sihao's deeds of the elderly exhibition was held in the new Hangzhou Library, and its bust bronze statue was also exhibited.

Wei Sihao, a retired teacher in Hangzhou, is known as the old man who washed his hands before entering the library. "Fame" originated from the photo of "Hangzhou Library is open to tramps, and scavengers wash their hands before reading" which attracted wide attention on June 20, 20041/KLOC-0. In the description of the photo, the author used a pen name, Zhang Kai (that is, Wei Sihao), and appeared again at the door of the reading room in the special literature area on the third floor of the aerial map, wearing the same clothes: a bamboo pole carrying two pockets on his shoulder. He unloaded his pocket at his desk and asked the staff to find some famous Chinese and foreign books. Although my eyesight is very poor, I still put the book in front of my eyes and read it with relish. "
