Chinese Buddhism could be classified into various subjects such as history of Buddhism, history of Buddhist Doctrines, history of translating Buddhist texts, Buddhist sects and the founders of specific sects. However, the most significant issue is that what are differences and similarities between Buddhism and Confucianism and Taoism. It is said that harmony with traditional Taoism and Confucianism by Buddhism which is a foreign religion was needed for being embraced and spreaded by ruling classed and populace in China It is natural in the process of spreading Buddhism that Buddhism adopted the methods and means which could be easily accepted by Chinese people. Buddhist Thoughts were transmitted into China beginning from translations by An Shigao(安世高) and Zhi Loujiachen(支婁迦讖) in the Later Han period and then the biographies of the Buddha and Mahāyāna sūtras continued to be translated in the Three Kingdoms period. Intellectuals who believed in Buddhism started to get interested in what the Buddhism is and the answer to this is the Mouzilihuolun(牟子理惑論) which is composed by Mouzi to solve the questions. The Mouzilihuolun(牟子理惑論) is, in this respect, thought that it shows the aspects of debate and harmony among the three religions which are seriously different from one another.
