Li Chu, king of Guangping, has been in history. Li Chu generally refers to Li Yu, the emperor of Tang Daizong in the Tang Dynasty. Tang Daizong Li Yu, formerly known as Li Chu, was the eldest son of Tang Suzong and the eighth emperor of the Tang Dynasty. His reign was from 762 to 779. First named Chu, formerly known as Chu, later renamed Chu. In 756 AD (Tianbao 15th year), An Lushan rebels captured Tongguan, Xuanzong fled to Mayi, and local people took Su Zong in, so they escorted him to Beidi Lingwu. An Shi Rebellion, in the name of Marshal, recovered Luoyang and Chang 'an. In 758 A.D. (the first year of Gan Yuan), he became king in March, and was appointed Crown Prince in April.

In 762 AD (the first year of Baoying), eunuch Li killed queen Zhang, and Su Zong was shocked to death. Before Su Zong's coffin, he acceded to the throne according to his will and changed his name to Yu. In 763 AD, the Anshi Rebellion was put down. He died in 779 AD, Emperor Xiaowu of Wen Rui, posthumous title. Buried in Yuanling (now Tanshan Mountain, 30 miles northwest of Fuping County, Shaanxi Province).

The social contradictions faced by Tang Daizong are complicated, and the tasks entrusted to him by history are very arduous. He has presided over state affairs for many years, and from the perspective of political achievements, he has made contributions, but on the whole, he has done more than he has done, which should basically be affirmed. His life is rich and colorful, with easy battlefield experience and power view, as well as ups and downs of competition on the political stage. Among the emperors of the Tang Dynasty, he was also called the sentimental son of heaven.
