Daizong’s appointment of Guo Ziyi was not considered wise, but he was not stupid either. When he was still the prince, Li Fuguo was in power and chaos and imprisoned the emperor Xuanzong of the Tang Dynasty. At that time, he ignored the major threats to his position as the prince. Regardless of the pressure from Queen Zhang and Li Fuguo, he rushed to the two palaces day and night to serve his grandfather and his sick son. My father always took care of himself with medicine and food, never took off his clothes, and was extremely filial to his relatives. He is a filial person. At that time, there were three major forces in the palace: Li Fuguo, Cheng Yuanzhen and Queen Zhang. Later, the Hou party was eradicated by the eunuch forces, Queen Zhang was killed, and Suzong died of fright. Li Fuguo supported Dai Zong to ascend the throne and took credit unreasonably. Daizong succeeded in planning the assassination of Li Fuguo. Later, when the Tibetan invaders invaded Chang'an and the Pugu Huai'en Incident, they were able to achieve a state of uncontrollable chaos. He also tried to reform the water transport and tax system and try to save the decadence. Such a monarch is not bad.
