1739), or Liu Chih, was a Chinese Sunni Hanafi-Maturidi scholar[1][2] of the Qing dynasty,[3] belonging to the Huiru (Muslim) school of Neoconfucian thought.

[4] He was the most prominent of the Han Kitab writers who attempted to explain Muslim thought in the Chinese intellectual climate for a Hui Chinese audience, by frequently borrowing terminologies from Buddhism, Taoism and most prominently Neoconfucianism and aligning them with Islamic concepts.

[5] His magnum opus, Tianfang Xingli or 'Nature and Principle in the Direction of Heaven', was considered the authoritative exposition of Islamic beliefs and has been republished twenty-five times between 1760 and 1939, and is often referred to by Muslims writing in Chinese.

From around the age of 30, he took up residence at the foot of Qingliangshan in Nanjing, where he began to interpret and expound on the Islamic scriptures, using Confucian studies, for a period of about twenty years.

During this time, he twice brought his manuscript with him to visit and solicit advice and the opinions of both Muslims and non-Muslims, leaving his tracks throughout Jiangsu, Shandong, Hebei, Henan, Anhui, Zhejiang, Guangdong, and other places.
