Welcome to Andy Lau's Hong Kong movie : Wait 'Til You're Older

This is an interesting movies and education movies

Wait 'Til You're Older casts (Andy Lau) as Kwong, the aged version of a young boy played by Sit Lap-Yin. Kwong (Andy lau) wishes to escape the tyranny of his stepmother Min (Karen Mok), who engaged in an affair with his father Man (Felix Wong) before the two married. Kwong's mother (Lee Bing-Bing) committed suicide in protest of the affair, meaning Kwong has a raging grudge against both Man and Min, and good cause for wanting emancipation from his morally-dubious guardians. Thanks to a miracle growth formula/plot device developed by a local quack (director Feng Xiaogang in a cameo), Kwong gets his instant aging wish.

Suddenly he grow up as an adult, Kwong spends time as an adult interacting with all the elderly people, namely his father and his teachers, but he does so in frequently roundabout and manufactured ways. Kwong passes himself off as his friend's older brother and proceeds to ingratiate himself into his father's life. He starts learning family secrets and get to know his father's inner emotions. He also gets an eyeful of complex adult relationships, as embodied by Miss Lee and her back-up lover status to assistant-principal Chow (Gordon Lam).

Whether or not he learns a lesson from all the meetings is unknown, what is known is other characters frequently spill their guts in front of Kwong. The difficulties of adult life are related to Kwong far too much. In growing older, Kwong should get to experience being an adult, and not just listen to endless lectures about it.
