Di Renjie can be said to be the savior of Tang Dynasty. Emperor Taizong passed the throne to Prince Li Zhi, but he was clever and confused. He didn't expect that his heir to the throne was a henpecked wife, and was played by his wife Wu Zetian. Cann't control my wife or a small matter. What is even more irritating is that through his hand, he actually gave his ancestors to Wu Zetian. The Tang Dynasty almost perished. Thanks to the efforts of De and others, Datang Jiangshan returned to Zhao's hands intact. Unfortunately, De Renjie, who saved the Tang Dynasty, was destroyed by the common people.

It is said that after Wu Zetian came to power, she vigorously selected talents. Emperor was not reused, but Wu Zetian had a unique vision, and soon realized the outstanding talent of Emperor, and promoted him as prime minister, thus making the official career of Emperor enter a glorious stage in his life. De Renjie is smart and capable, not only loyal to the imperial court, but also proficient in official career and good at self-protection. In the fierce power struggle during the period of Wu Zetian, he always occupied a high position and was deeply loved and trusted by the queen. However, with the calculation and means of Wu Zetian, it is no match for Di Renjie. Di was the staunchest backbone of the restoration of the Tang Dynasty. He took advantage of Wu Zetian's trust in himself and always planned to restore the Tang Dynasty.

According to the Book of the New Tang Dynasty, Wu Zetian once discussed the choice of a prince at a court meeting. The ministers knew the queen's worry and agreed to let the descendants of the Wu family be princes. At the critical moment, the Emperor stepped forward and said,' I think the whole world still misses the Tang Dynasty, and the candidate for the prince must be Li Xian, the king of Luling. In a word, Wu Zetian was very unhappy and the meeting broke up in discord. Seeing that Wu Zetian was old and the succession was imminent, Di Renjie began to spare no effort to restore Li Xian's status as a prince. In the end, Li Xian was able to become a justified prince and made his first contribution to the revival of Li Tang. ?

Di Renjie is a clever man, but he has a son who lives up to expectations. This son, Di Jinghui, was also an official in North Korea, and later worked as a military attache in Weizhou. Di Jinghui's character is far inferior to his father's. Not only is his talent average, but he is also greedy and tyrannical, and he acts illegally, which has become the harm of Weizhou. Di used to be the secretariat of Weizhou. He loves people like a son and solves problems like God. His official voice is very good. People built an ancestral temple for him in the local area to show their respect and gratitude.

The Book of the New Tang Dynasty records that his son Di Jinghui offended the people, who expressed their dissatisfaction in order to vent their anger and "destroyed Ren Jie's shrine". Because he hated his son, he got into trouble with his father and broke the ancestral hall of Di Renjie. It was not until a few decades later that the field was rebuilt after guarding Weizhou.
