Why is Di A Qing a fairy?

Because according to legend, the Jade Emperor sent Wen Quxing and Wu Quxing to protect the Emperor of the Song Dynasty. There was a famous soldier named Di Qing in the Northern Song Dynasty. He is known as the "invincible army god" of the Northern Song Dynasty! General Di Qing was a legendary figure in the military field in the Northern Song Dynasty. When he was young, he committed a life-threatening lawsuit for his brother. Because of his diligence and courage, he gradually rose in the military field and eventually became an official in the Tang Dynasty! He was the only person in the Song Dynasty who was promoted from a soldier to the commander-in-chief of the imperial army. So Di Qing is a fairy.
