it cannot be her husband's because his is small; he cannot recognize her because his eyesight is failing. While they are having sex, he takes a close look at her figure and nipple and recognizes her. To her dismay, he screams, shouts and calls her a disgrace. To his dismay, she runs off and hangs herself. Yeung-Sheng, completely broken, goes back to the monk to ask for forgiveness. Box office In Hong Kong, the film grossed HK$18,424,224. This was enormous business considering the film was saddled with the restrictive Category III rating (the Hong Kong equivalent of NC-17 in the US). Sequels Sex and Zen went on to spin off two sequels, Sex and Zen II and Sex and Zen III. These are not sequels in plot, as each movie illustrates a different story also based on the sex manual.
