Cai Bo and Yan Shu were both Bandu of Song Renzong's childhood. Why didn't Yan Shu get the reuse of Injong and Cai Bo?

Song Zhenzong asked Cai Bo and another prodigy, Yan Shu, to study with Prince Zhao Zhen. For the present situation that the prince doesn't like reading, the practices of the two accompanying children are quite different. Yan Shu tried to dissuade Zhao Zhen, while Cai Bo tried to cater to him.

Cai Bo was deeply puzzled by this, so he went to ask Song Renzong Zhao Zhen and replied, "The son of heaven should use people with both ability and political integrity. Compared with Yan Shu, you have talent and no virtue. " Cai Bo _ was speechless after hearing this. I didn't expect the flattery when I was young to be remembered by the prince. Who knows that from then on, he not only did not repent, but intensified, often doing things that were despised by people.

Out of the deep friendship established when he was young, Song Renzong did not pursue Cai Bo excessively, and Cai Bo was never taken seriously. At the age of eighty, he was just a small farmer.

Extended data:

Because the threshold of the palace is too high, when the prince is difficult to cross, Cai Bo even directly lies down as the prince's cushion, writing articles for Prince Zhao Zhen to cope with Song Zhenzong's inspection.

On one occasion, Song Zhenzong asked Cai Bo whether he missed his parents, and Cai Bo said directly, "The emperor is my parents." Song Zhenzong was very satisfied. In the process of accompanying the prince, Cai Bo showed his flattery incisively and vividly, but his flattery did not bring him any benefits, but arranged some idle jobs for him.
