In general, there was little intersection between harem concubines and former court ministers.
However, it was precisely at the end of The reign of Emperor Renzong of Song and the beginning of the reign of Emperor Yingzong of Song that two major events occurred, which left a deep impression on the hearts of the anti-reform faction cadres in the hearts of Emperor Renzong's empress Cao and Emperor Yingzong's empress Gao.

These two things, one is Emperor Renzong's lipu, and the other is Emperor Yingzong's discussion, which is both independent of each other and related: Emperor Renzong was lustful all his life, worked tirelessly, and left more than a dozen children, but the prince only had three, and they all died early! As a result, his health deteriorated in his later years, and the ministers wanted him to find someone in the clan to succeed him. However, Renzong thought that he still had a chance, and he could still be born! As a result, from the beginning of the Zhihe period, Emperor Renzong and his ministers engaged in a fierce debate on this issue, but everyone was never able to persuade Emperor Renzong. Finally, in the sixth year of Jiayou, the prime minister Han Qi transferred Sima Guang to the central government, let him know the court, and led the entire Taiwan advisory system to give emperor Renzong strong advice again and again, and persuaded Emperor Renzong to nod his head and pass on Zhao Zongshi, the son of Zhao Yunrang, the prince of Pu, that is, Gao's husband, later Song Yingzong. Later, when the DPRK and China discussed the merits of Li Chu, everyone concluded that the "first merit of Fan Zhen" was "the first merit of Fan Zhen" at the end of the reign, and the Zai officials during the Jiayou period "stopped using the counselor Sima Guangzhangshu", which was regarded as the main credit. In other words, if it were not for Fan Zhen and Sima Guang, it is unknown whether Emperor Yingzong would have been able to sit on the throne of God and whether Gao Shi would have become this empress. Fan Zhen and Sima Guang, on the other hand, are both staunch anti-degeneration factions.
This matter is not over, after Emperor Yingzong succeeded to the throne, his mind was active, opening the "Pu Discussion" and asking everyone to discuss how to call his biological father Zhao Yunrang, the King of Pu. At this time, Sima Guang and Fan Zhen and others stood very firmly against the emperor: they believed that since Emperor Yingzong had already passed on to Emperor Renzong, although King Pu was your biological father, he had nothing to do with you, so he could not be honored as "Emperor Kao", but could only be called "Emperor Uncle", and strongly defended the interests of Emperor Renzong, so he left an excellent impression in the heart of Emperor Renzong's empress Cao!
Therefore, later, the Cao and Gao clans always cared for Sima Guang and these officials of the anti-reform fa faction, and they had the intention of maintaining them. After the death of Emperor Shenzong, gao shi bowed to the government, and immediately remembered that Sima Guang and Fan Zhen were ordered to promote and reuse them, so that the anti-degenerate officials could quickly make a comeback in the dynasty. At the end of May of the eighth year of YuanFeng, Sima Guang was appointed as a subordinate attendant, that is, a deputy prime minister, while the prime minister Cai Qing, who supported the change, was appointed as Emperor Renzong's envoy and temporarily left the central government. On June 14, Sima Guangshangshu asked for the opening of the road of speech, and on the twenty-sixth day, Shangshu recommended the two brothers Su Shi and Su Rui. In the same month, Fan Chunren, Lü Gongzhuo, Lü Dafang, Wang Cun and others also recommended these two brothers, and Su Shi rode on this shareholder wind and went straight into the clouds.
