Nine Ministers
Knowing that the conservative noble classes occupied every level of the Han court, Emperor Wu changed his strategy. He secretly recruited a circle of young loyal supporters from ordinary backgrounds and promoted them to middle-level positions in order to infiltrate executive ranks in the government. These newly established officials, known as the "insider court" (内朝), took orders and reported directly to Emperor Wu. They had real influence over the operation of government affairs though lower in rank. They became a powerful counter against the "outsider court" (外朝) made up of the Three Lords and Nine Ministers that, at the time, were mostly composed of anti-reformists. Furthermore, Emperor Wu sent out nationwide edicts appealing to grassroots scholars such as Gongsun Hong to enrol in government services in an attempt to break the stranglehold that the older-generation noble class had on the nation's levers of power.
