Ouyang Xu's good friend and school teacher.I am highly myopic and cannot see clearly without my glasses.Although he was very knowledgeable, he was pedantic. He went to persuade Zhao Pan'er to become a concubine, but was later taught a lesson by Sun Sanniang.Finally, after experiencing some things, I changed my view on Sun Sanniang, and I also learned about Sun Sanniang's experience, and I have a deep affection for her.
