Factual error: When master Shifu is trying to show Po how to do a perfect split, Tigress breaks clay over Po's head. Violating the laws of physics, the larger piece of the clay falls last and the powder of the clay falls first.
Continuity mistake: When Shifu performs the Wuxi finger hold on Po, in one shot, we see all of Po's fingers, except the one Shifu is holding, are closed to his palm. In the next shot, all his fingers are open. (00:22:05)
