I have read both of Hsi Lai's books, Tigress and Green Dragon. He brings forth long repressed
materials from very old sources. The repression mainly came from the moralism and spiritual oppression emanating after taoism, thru confucianism then thru communism. Rather than female vampirism
these writings free women and provide routes of sexual expression which actually reduce the risk
of STDs. I, for one, will explore this more.
