Initially, the official He Yuanliang (和元亮) served as Li Yong's teacher, but as He was a career soldier, when Emperor Wenzong met He to discuss the prince's education in 832, He was unable to respond well.
It was said that, however, when Wei was set to tutor him in the morning, it would often been the case that he would not get to see Li Yong until the sun was high in the sky.
[5] Meanwhile, by 838, Li Yong's mother Consort Wang had died—and while the exact manner of death was not clarified in historical accounts, it was said that she was not favored by Emperor Wenzong and that Emperor Wenzong's favorite, Consort Yang, made false accusations against her, leading to her death.
Despite this, Li Yong continued to spend his time on feasts and games and was close to scoundrels.
[6] On September 29, 838,[1] Emperor Wenzong suddenly had Li Yong arrested and convened a gathering with imperial officials, listing Li Yong's faults and intending to depose him, stating, "How can this kind of person be the Son of Heaven?"
That night, Emperor Wenzong released Li Yong and allowed him to return to Shangyang Pavilion (上陽院), where the Crown Prince resided.
[7] He was buried with honors due a crown prince and given the posthumous name of Zhuangke (meaning "unsuccessful and respectful").
