Lord Pingyuan of Zhao vs Sang Hongyang

Lord Pingyuan maintained a household of three thousand retainers, including scholars, strategists, and assassins. This patronage network made him one of the Four Lords of the Warring States and a center of political and intellectual activity.

Lord Pingyuan (Zhao Sheng) organized the defense of Handan, the Zhao capital, during a prolonged siege by Qin forces. He sent envoys to Wei and Chu for aid, and the city was eventually relieved by allied forces, preserving Zhao's independence.

Sang Hongyang established government monopolies over the production and sale of salt and iron. These monopolies generated substantial revenue for the Han treasury, enabling Emperor Wu's expansionist policies, but also faced criticism for stifling private enterprise.

Sang Hongyang introduced the 'equalization and standardization' (junshu) system to stabilize prices and transport goods. The government bought surplus goods in regions of abundance and sold them in areas of scarcity, controlling commerce and increasing state revenue.

Sang Hongyang was appointed as Superintendent of Agriculture (Da Sinong) under Emperor Wu of Han. He became the chief financial officer responsible for implementing state monopolies on salt, iron, and liquor to fund military campaigns.

After Emperor Wu's death, Sang Hongyang was accused of conspiring with the regent Huo Guang's rivals. He was executed along with his family, ending his economic reforms temporarily, though many were later reinstated.
