Song and Yuan period, Islam in China has not yet fixed translation. Later, Muslim scholars, according to the Islamic belief in God, the doctrine of cleanliness, more choice of "halal", "clean" kind of words translated into Islamic or worship temple. Legend has it that the Xi'an Daxuexiang Mosque, which was built in the Tang Dynasty, was initially known as the "Pure Temple", and in the Yuan Dynasty, Saidian Chi? Zhan Si Ding also played to change the "mosque" for "mosque", the first year of the Ming Emperor Hongwu (1368) inscription Jinling Temple of Worship "Hundred Characters of Zan" in the "name of the religion of the Qingzhen", indicating that the mosque has become a form of Islam at that time. At that time has become a common name for Islam. In the late Ming and early Qing dynasties, Muslim scholars with traditional Chinese cultural training systematically interpreted the meaning of "halal". Wang Daiyi said, "Purity and unadulterated purity are called Qing, and sincerity and unity are called truth." He also said, "The essence of halal is to follow the order and recognize the God of creation." Wang Daiyu's interpretation of "halal" here is actually an interpretation of Islam. Many scholars on their own translation of the work on Islam is also titled "halal" word, such as "Halal University", "Halal Guide" and so on.
