Why did the female ghost give the fifth set of RMB at the beginning of Ghost Summer Vacation (1992) played by Chen Kui 'an?

That means the film is not 1992, and the red 100 yuan bill is 1999, so the film will not be released before 1999. Baidu's information is incorrect, and it can be seen that Chen Kuian's age does not match. You can refer to him. Also, 1992, there should be no 3P air conditioner in China.
