Viceroy of Liangguang
Ruan Yuan was a successful official as well as a scholar. He was the Viceroy of Liangguang, the most important imperial official in Canton (Guangzhou), during the critical years 1817–1826, just before the First Opium War with Britain. It was a crucial time when Chinese trade with the outside world was allowed only through the Canton System, with all foreigners confined to Canton, the capital of Guangdong Province. During his tenure in Canton, Ruan is estimated to have earned more than 195,000 taels of silver.
