When Yu gets hit with a tea-cup in the face (as in with enough force to shatter against his skull) he doesn't even blink. Literally.
The initial fight between Tsao and the head of East Bureau. It starts by Tsao heaving logs at his heads only for the head to knock them back with his fists. It gets crazier from there.
Feng may be the buttmonkey of the film, but in the end, he's ultimately the one to takedown the true antagonist of the film, and furthermore, he's the only character who ends up better than they started, getting together with the innkeeper and overall the two of them are the only ones in this film who don't have a bittersweet victory or downer ending.
