-----After persuading him, Di Ren said: The two Zhangs (brothers Zhang Yizhi and Zhang Zongchang) are at your majesty’s side, and they really have a bad reputation for the emperor. What a pity.
Wu Zetian said: You are a loyal and honest minister, so I entrust you with the important responsibilities of the country, but it is not appropriate for ministers of the emperor to interfere with personal affairs. He also said that I didn’t want to favor Er Zhang, but just for my own health. I used to serve the late emperor and had too many children. My blood was exhausted and I was often plagued by illness. Although I often took supplements such as ginseng antler, I still couldn’t. The effect is not big. Now only by taking Yuan Yang and taking the basis of bacon, can Yin and Yang be combined and the blood and Qi be sufficient. I didn't believe it at first, but after giving it a try, it turned out to be really good. You see, I am over seventy years old, and I have two new teeth.
It has risen to the political level of the emperor taking care of the dragon body, and it is related to the emperor's spring and Autumn period, so Di Renjie stopped trying to persuade him. But Wu Zetian also understood what Di Lao meant, and from then on, except for "Er Zhang" around her, she never found any other male favorites.
The above materials are all public conversations in the court. This shows that Wu Zetian is still a very generous person, and he can clearly distinguish the importance of important ministers and pets.
