Guan Zhong started multiple reforms in the State of Qi. Politically, he centralized power and divided the state into different villages, each carrying out a specific trade. Instead of relying on the traditional aristocracy for manpower, he applied levies to the village units directly. He also developed a better method for choosing talent to be governors. Under Guan Zhong, Qi shifted administrative responsibility from hereditary aristocrats to professional bureaucrats. He is also credited for creating the first official government sponsored brothel known as "女市" which funded the government treasury.
