The wuxia genre is popular in Chinese culture because it is the unique blend of martial arts philosophy of xia (俠, "chivalry", "a chivalrous man or woman") developed throughout history, and the country's long history of wushu. In Japan, samurai bushido traditions share some aspects with Chinese martial xia philosophy. Although the xia or "chivalry" concept is often translated as "knights", "chivalrous warriors" or "knights-errant", most xia aspects are so rooted in the social and cultural environment of ancient China that it is impossible to find an exact translation in the Western world.
