Is Yuan Shushan a teacher in Ching-Ying Lam?

When Ching-Ying Lam studied with Ju-hua Fen in the troupe, Yuan Shushan was his literature (learning culture) teacher, and he also studied Taoism with Yuan Shushan. Yuan Shushan died on 1968, before Ching-Ying Lam entered the entertainment circle! As for who Ju-hua Fen is, ask Du Niang, there is a brief introduction in Baidu.
