Wang Chang
Wang Chang noticed that his base at Wancheng was too far away from Xiangyang, an important city on Wei's southern border. Besides, the military camps in that region were quite scattered and their naval force was far away at Xuanchi. If enemy forces from Wei's rival state Eastern Wu attacked them, their armies would not be able to provide support in time. Hence, Wang Chang changed his base to Xinye, ordered drills to be conducted for their naval forces, and promoted agriculture to build up food supplies.
