For example: the most famous De Renjie. Are they loyal or treacherous? Everyone will say that De Renjie is absolutely loyal. That's great. Here comes the problem. Wu Zetian established the Zhou Dynasty. Can De Renjie accept and be loyal to Da Zhou? If the answer is: Yes. Therefore, Di Renjie was a traitor in the Tang Dynasty. If the answer is: Emperor is a loyal minister of Datang, then Emperor is unfaithful to Da Zhou. So is Zhang Jianzhi. Zhang Jianzhi is the planner and executor of the Dragon Coup. He forced Wu Zetian to abdicate. Can you say that such a person is a loyal minister? The same is true of Wu Sansi and Lai Junchen. Everyone said they were treacherous court officials. That's because they bring disaster to the country and people. But it is unreasonable to say that they are not loyal to Wu Zetian. Their persecution of the royal family in Li Tang was their loyalty to Wu Zetian and the Zhou Dynasty.
Does that mean that during the reign of Wu Zetian, loyal subjects and traitors could not be distinguished? Of course you can't say that. What is loyalty and what is betrayal? That depends on the minister's attitude towards the country and the people, not the emperor. That is to say, the people are the most important, the country is the second, and the monarch is the light.
So as far as the rule of Wu Zetian is concerned.
Loyal ministers: Di, Wei, Zhang Jian, Yao Chong, Song Jing, Pei Yan, Princess Taiping, etc.
Treacherous court officials: Wu Sansi, Suo Yuanli, Lai Junchen, Zhou Xing,,,, Yu, Li Yifu, etc.
Wu Zetian's loyal minister (who is personally loyal to Wu Zetian but has no great harm to the country, and who attacks Wu Zetian's political enemies: Xu He.
Loyal "loyal ministers" regardless of life and death: Luo, Li Ai, Li Zhen, etc.
