 Sings failed attempt in intimidating a Pig Sty village farmer, who punches   him square in the stomach. The Hong Kong version shows Sing spitting out   blood, which ends up appearing on the farmers face after Sing asks her what   she does. The American version digitally removes both the blood being spit   out (but blood is still seen around his mouth implying it was "coming up")   as well as the blood splats on the farmers face.
