Actually, there has been a "stamp collecting actress" for some time. When Wu Junru was interviewing Andy Lau in the radio program "Stars Alumni Association" in Hong Kong, she revealed that there is an actress in the entertainment circle who regards sleeping with popular male stars as a hobby. Among the Four Heavenly Kings, she has already "collected" three of them, but only Andy Lau rejected her. While people were still guessing who this actress might be, Song Zude then claimed on his blog that: Niki Chow has had multiple close collaborations with the Four Heavenly Kings, and she is the "stamp collecting actress".
