The Queen Bee [1973, Hong Kong, thriller, DVDRip] VO

Xiao Yan arrives to work as a nanny in a wealthy household. There, she encounters a menacing housekeeper, a former nanny who has gone mad, and a beautiful and alluring mistress. The outwardly glamorous and wealthy mistress is promiscuous, frequently attracting the attention of philandering men and indulging in sexual pleasures. But these men usually disappear without a trace afterward. One day, a frightened Xiao Yan mistakenly enters the mistress's room and witnesses her having an affair with the driver. The driver initially tries to kill Xiao Yan but eventually tells her everything. It turns out the mistress has had such relationships with hundreds of men, and the driver was one of them. A few days later, the driver vanishes, along with all those who had been with the mistress. The cold, eerie mansion, the beautiful mistress, and the ghost of the mansion's deceased master, who had been dead for many years, "appear"—the truth is chilling, and the atmosphere is utterly bizarre.
