How do you objectively evaluate Bao Zheng?

The real Bao Zheng, with a well-off family, only worked in Kaifeng for about a year and a half. The old man is honest and honest, and he is an absolute courtier. The likes and dislikes of all beings should not be used as a standard to measure the merits and demerits of personal values. Objectively speaking, there is absolutely no problem with personal morality, but he is not a first-class politician. Of course, the political atmosphere in the Song Dynasty is another matter. Tell you a little thing, Sima Guang and Wang Anshi used to work in Kaifeng. The leader of the two is Lao Bao, who invited guests to propose a toast. As a result, Sima Guang, a teetotaler, had a drink, but Wang Anshi resolutely refused to drink it.
