That friend recommended several novels about Ma Xian. Thank you.

The best novel I've ever seen dedicated to Ma Xian is , but when I read it, I think it's very general and a little unfinished ... As a novel, the best one should be Cui Zouzhao's My Years as a Teacher of Yin and Yang and Jumping God, which are not all about Ma Xian, but have some other elements but are very beautiful and touching; There's another book called < >, but it's not the same author as the first two, and it's not bad. There is also a legendary experience called < >, so-so. That's all I know. I wish I could help you, dear.
