In the program "Stars Alumni" aired the other night, Ruby Wu exposed sensational anecdotes about a "philatelic actress" in the circle, which made netizens guess who she was. In the program, Ruby Wu said that there was an actress in the circle whose hobby was to sleep with male stars, just like collecting stamps. She also claimed to Ruby Wu that she had collected three of the Four Heavenly Kings. When Ruby Wu quietly told the guests who the "philatelic actress" was, Du Wenze was scared and shouted: "The microphone is still on, it hasn't been turned off yet!" The scene was hilarious.
