At the end of the Eastern Han Dynasty, Cao Cao, in order to supplement military pay, initiated the official tomb-raiding practice and established the first professional tomb-raiding force in Chinese history. He set up four positions: the Treasure Mover, the Qiu Zhonglang General, the Mountain Moving Taoist, and the Mountain Unloading Warrior. Each position had different specialties and performed their own duties. Later, these positions evolved into the four major schools in the Chinese tomb-raiding world.
