After experiencing a series of incidents such as fratricide, court strife, and border wars, he gradually became deep, reserved, and scheming. On the one hand, he wanted to maintain imperial power and consolidate his rule; on the other hand, he wanted to balance the forces of all parties and prevent civil strife in the court. In the process, he lost many precious things, including friendship, love and family affection. In the end, he became a lonely emperor, but he also brought short-term prosperity to the Jiuding Dynasty.
