Abstract："Qi Chu" was the most common divorce institution in ancient China. It first appeared in the Confucian classics and became a formal institution in Tang dynasty. As a matter of fact, "Qi Chu" did not ignore women's interest entirely. "Qi Chu" allowed the husband to divorce his wife based on seven reasons and restricted the previously unlimited power of the husband to divorce his wife and in actuality, sheltered women's marriage. According to the Tang Code, the essential prerequisite of applying the "Qi Chu" is to prohibit the husband from arbitrarily divorcing his wife and in effect, safeguarded wives who did nothing wrong. Though the husband was able to divorce his wife by the institution of "Qi Chu", the rule of "San Bu-Qv" restricted him from divorcing women and instead made him respect women who conducted good deed for the his family and protect the interests of the weak and helpless women.
