The Records of the Three Kingdoms describes Cao Cao as a hero who "devised and implemented strategies, lorded the world over, wielded skillfully the law and political technique of Shen Buhai and Shang Yang, and unified the ingenious strategies of Han Fei". Zhuge Liang also attached great importance to the works of Shen Buhai and Han Fei. The tendency toward Legalism is apparent in intellectual circles toward the end of the Han dynasty, and would be reinforced by Cao Wei. Dispossessed peasants were organized into paramilitary agricultural colonies to increase food production for the army, and penal legislation increased. These policies would be followed by the Northern Wei.
