Andy Lau, who weighs 300 pounds, and Sammi Cheng, who weighs 260 pounds, are practicing leapfrog on the slope.

Slimming Men and Women is ingenious, portraying Andy Lau and Sammi Cheng as super fat girls. Instead of using computer stunts, Du Qifeng invited Hollywood makeup artist Steve to make special plastic models of fat people for Andy Lau and Sammi Cheng, and the effect was realistic. In the movie "Slimming Men and Women", Andy Lau made a 45-day crash slimming plan for Sammi Cheng, and the process of slimming in purgatory produced many jokes.
