Vanishing Son 2 - Russell Wong (1994) - Yuen Yuen Institute, Tsuen Wan

Vanishing Son 2 picks up where the last film left off and this time treats Wong's character as some sort of wandering Bruce Banner type character (I'm talking of the Bill Bixby days) who doesn't go looking for trouble but is ready to step up when it appears. 99% of this film is set and filmed in the US, but there is a single flashback scene filmed at one of the first film's Hong Kong locations - the Yuen Yuen Institute. It looks as though all four films in this TV movie series were filmed back-to-back.
