After Won Fei Hung is beaten by Thunderleg and offered Beggar Su some wine, he drops the bowl, and Su catches it. If you slow-mo the DVD, for a split second you can see that the bowl goes past Su's foot, which is coming up to catch it. The film then cuts to a shot where the bowl is on Su's foot.
In the 2002 DVD Edition, Wong Fei-Hung is made to stand in the horse stance. His friend puts a chair under him. His father returns and sees the chair. As the father is walking up to Wong Fei-Hung the chair is missing. Then his father kicks the chair out from under him.
