Europe[edit]

China[edit]

  • An Uyghur Turk sues the son of a Chinese general, who had failed to repay a debt of 11 million government-issued copper coins. Emperor Wen Zong 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.
