According to the biography of Li Zhuan in Records of Shu 12, Li Zhuan's courtesy name was Qinzhong and he was a man of Fu County in Zitong Commandery. His father Li Ren, courtesy name Dexian, went to study in Jing Province together with Yin Mo of the same county and learned from Sima Hui, Song Zhong and others. Li Zhuan received that learning in full, and also discussed principles under Yin Mo, so that there was nothing in the Five Classics and the works of the philosophers that he had not read. Records, Shu 12 §46
He also had a wide liking for various arts, and applied his mind to the skills of arithmetic, divination, medicine, crossbows and machinery. He first became an Assistant Clerk of the province and a Clerk of the Masters of Writing. Records, Shu 12 §46
In the 1st year of Yanxi (238), when the Later Sovereign (Liu Shan) established the crown prince, Li Zhuan was made Cadet of the Crown Prince and then moved to Supervisor (puye), and he was transferred again to Palace Grandee (zhongsan dafu) and General of the Household of the Right but was still made to attend the crown prince. The crown prince prized his wide knowledge and was very fond of him. But because he was frivolous and rash in his bearing and liked jokes and teasing, the world did not take him seriously. Records, Shu 12 §47
Li Zhuan wrote commentaries on the old-text Changes, Book of Documents, Mao Odes, Three Rites and Zuo Commentary, as well as the Taixuan Zhigui, all of which took the Han scholars Jia Kui and Ma Rong as their standard and differed from Zheng Xuan. He was far removed from Master Wang and had never seen his writings, yet the conclusions of their meaning were largely the same. Li Zhuan died in the Jingyao era. Records, Shu 12 §47
In his assessment in Records of Shu 12, Chen Shou said that Xu Ci, Meng Guang, Lai Min and Li Zhuan were widely read and had heard much, and that Yin Mo was versed in the Zuo Commentary; although they were not praised for virtuous conduct or achievement, they were truly all scholars of their age.
