Audio problem: During the avalanche, Mulan's horse makes the exact same sound when galloping on dry hard ground and when he gallops on soft snow.
Audio problem: Mulan slips on the roof and tiles fall. No crash or any sound whatsoever is heard. (00:02:52)
Answer: Although it isn't said (in either this film or the animated original), she reports to a different camp than anyone else in her village. Otherwise, the men would not only recognize her physically but they would know beforehand that Hua Zhou never had a son so the ruse would never work. How she knows nobody from her village will be at that particular camp is never explained in either film.
