Shaolin Chastity Kung Fu (1981, Taiwan). Director: Robert Tai.
TBH, this movie is NOT one of my favorites. IMO, the fight choreography is uneven, and the storyline and pacing are so-so. But I feel there are a few things that were unique in a movie. This movie features Tongzi (child) Gong (or ‘kung’, same as in ‘kung fu’, meaning skill developed through hard work). The kids in the movie were clearly young Peking Opera students in real life.
This movie also features two of the kung fu movie actors whom I personally knew in Taiwan. The female co-star, Liu Hao-Yi, and Jian Xun, who played the young adult Shaolin monk.
Some trivia: A poster for Shaolin Chastity Kung Fu is briefly visible in a scene in the Madonna movie ‘Desperately Seeking Susan’.
Tongzi Gong training scenes, featuring Chang Chi-Ming (the Shaolin Abbott), Alexander Lo Rei, Liu Hao-Yi, Jian Xun, William Yen, etc.:
Fight: Jian Xun (the Shaolin Monk) vs Yang Hsiung:
The man playing the arch-villain wearing the fedora, Tang Lung, and leading star Alexander Lo Rei, are actually brothers in real life. Their initial one-on-one fight isn’t bad, but IMO, the part where the children start singing is cringe-worthy.
Final fight: Alexander Lo Rei, Jian Xun, William Yen, etc., vs Tang Lung:
