I believe everyone is no stranger to Yan Yan, who has appeared in many films and television works of the Three Kingdoms. It is not too much to say that Yan Yan is a famous general. Then why didn't you make any contribution after playing for Shu? Let me talk about my own views on this issue.

1 has a certain reputation, but her position in Shu is not high.

Yan Yan was originally a general under Liu Zhang and Liu Zhang's right-hand man. At that time, Zhang Fei led an army to attack Liu Zhang and met Yan Yan's resistance. Despite the disparity in strength between the two armies, Yan Yan refused to surrender. When Zhang Fei broke into Yan Yan City and even beheaded Yan Yan, Yan Yan did not give in. Later, Zhang Fei took a fancy to Yan Yan's loyalty and left Yan Yan as a guest. In fact, his position in Shu is equivalent to an ordinary door guest, so where does he go to make contributions?

Yan Yan refused to play for Shu.

As we just said, being forced to behead and refusing to surrender shows that he really doesn't want to give advice to Shu. Even if he became Zhang Fei's guest, it was not his choice. So even if he has the ability, as long as he doesn't want to contribute to Shu, then he naturally won't get credit.

Therefore, it is normal to have no credit after arriving in Shu. Because he doesn't want to make contributions to Shu himself, and his position in Shu is not high, even if Zhang Fei takes a fancy to his talent, he doesn't have much chance to make contributions to Shu.
