Continuity mistake: After Mulan breaks the winged sculpture she chases the chicken and runs past a couple. A mere second later Mulan is in a different place: the stuff on the wall has vanished, the ladder and, of course, the couple. There's a brief shot afterwards where you can now see the ladder but the couple is nowhere to be seen. The whole editing is a mess.
