Han Wudi built an imperial university that prepared young men. The Confucian educational system was the name of the system used.
Han Wudi had a foreign policy of imperial expansion. He conquered northern Vietnam and Korea. The hardest challenge that Han faced in foreign policy was dealing with the Xiongnu.
The land in the Han dynasty was owned by the wealthy class. This resulted in social tention and rebellion.
The most important reform that Wang Mang issued was the land property reform. This reforn stated that only a certain amount of land can be given to a family. The resultof this was tensions rising between the landlords and the goverment. Ultimately Wangs people revolted against him ending his dynasty.
