How many movies did Detective Chinatown 2 plagiarize?

1. "Double Eyes". The plot settings and routines are very similar, and the setting of Feng Shui Five Elements Detective is almost exactly the same as the plot of "Twin Eyes".

2. "Police Academy". Wang Baoqiang was forced to dance a section that was highly consistent with the "Blue Oyster Bar" part of the classic routine in "Police Academy".
