Emperor Wenzong creates his son Li Yong crown prince in 832.

(Emperor Wenzong had previously planned to create Emperor Jingzong's oldest son, Li Pu the Prince of Jin, crown prince, but Li Pu had died in 828, and it is said that Emperor Wenzong was so bereaved that he had waited for four years before creating Li Yong crown prince.)

In this year, an Uyghur Turk sues the son of a Chinese Tang Dynasty grand general who had failed to repay a debt of eleven million government-issued copper coins.

Emperor Wenzong of Tang soon hears the news, and is so upset that he not only banishes the general, but attempts to ban all trade between Chinese and foreigners except for goods and livestock.

This ban is unsuccessful, and trade with foreigners resumes, especially in maritime affairs overseas.
