In the second month of 81 BC, the Han court held a debate on the state monopolies of salt and iron. On one side stood government officials led by the Imperial Secretary Sang Hongyang. On the other stood more than sixty “worthy and learned” men chosen from across the realm.
Under Emperor Xuan, the official Huan Kuan polished and expanded the records into a book, Discourses on Salt and Iron, in 60 chapters. A line often quoted from it reads: “In ancient times, people valued virtue and despised profit, prized righteousness and made light of wealth.”
