Sorry if this has already been brought up in the past, but I was just reading Yanie's XAJH 2001 review and agreeing with most of what was written when I came upon the section on the serial's "feminine males":
Mao Weitao is actually a female.Special mention to Mao Weitao (DungFang BuBai), Wei Zi (Yue Buqun) and Li Jie (Lin Pingzhi). These men have to portray feminine guy characters in the end after mastering kungfu manuals (Kuihua Baodian and/or Pi Xie Jian Fa). They portrayed it VERY well! Not too much, not less, just perfect. Mao Weitao is very pretty with that make-up on, one hardly can tell he's a REAL man.
