Before Michael Mak’s Sex And Zen became a cult favourite in the ’90s, there was Ho Fan’s Yu Pui Tsuen (The Carnal Prayer Mat, 1987). But without sex bomb Amy Yip, coarse humour or lesbian love affairs, Yu Pui Tsuen had to rely on the nudity and sex from his cast of relative unknowns to save the day. When a young man dreams that he drowns after a night of carnal passion, he asks a buddhist monk to translate the experience for him.
