The Battle of Sha Chia Bund, Hong Kong film from 1968.

Yang Mengchi is a spoiled, rich do-nothing whose habit of smoking opium has cost him his entire fortune and the family mansion, the Garden of Repose, now due to be sold to Yao Guodong. Fearing that Yao's spoiled and unruly son Siaofu will follow in Yang's footsteps, Yao's stepwife Wan Zhaohua tries to instil discipline in the child but her efforts are undermined by the child's indulging and protective father and grandmother. Unable to reform himself despite his own son's chastisement, Yang leaves home to lead a reclusive life in a destitute temple, only helped out by his filial daughter Han'er. The poverty-stricken Yang is drafted into the army and tragedy ensues.
