In the Tang Dynasty, Xue Dingshan, son of Xue Rengui, was killed by a traitor and his whole family was executed. Xue Dingshan's eldest son Xue Yong and second son Xue Meng were trapped in feudal morality and were killed in the city. Xue Gang, the third son of Xue Dingshan, was a strong man and refused to give in. He offered sacrifices to the Iron Qiu Tomb three times to protect the King of Luling, and finally raised an army to rebel against the Tang Dynasty, avenging a sea of blood so that justice could be done.
