Li Ao (philosopher)

Li Ao , courtesy name Xizhi , was Chinese philosopher and prose writer of the Tang Dynasty. He was born in present-day , but some accounts relates he was from . After achieving the degree of Jinshi in 798, he joined the imperial bureaucracy and served in the history department at Changan.

In 809, he was assigned to the southern provinces and made the trip with his pregnant wife from Luoyang to Guangzhou over nine months. The course they took included the modern provinces of Henan, Anhui, Jiangsu, Zhejiang, Jiangxi and Guangdong. His record of the trip, the ''Lainan Lu'' , contains detailed descriptions of medieval southern China and is considered one of the earliest forms of the diary.

At the time of his death in , Li held the position of Governor of East Shannan Circuit . There is some debate about the year of his death. The ''Book of Tang'' gives the date of 841. While the Qing Dynasty historians, however, have argued that it should be 836.

Late imperial scholars regarded Li as the founder of one of the ten great schools of philosophy in the Tang and dynasties. As a philosopher, Li was heavily influenced by Buddhism and also the great neo-Confucian Han Yu. His extensive writings are preserved in the ''Liwengong Wenji'' . This work is presumably a later edition of the ten chapters of the ''Li Ao Ji'' as referenced in the ''New Book of Tang''. Some of the few poems he produced can also be found in the ''Quan Tang Shi'' .
