The Wagang Army uprising led by Zhai Rang opened the prelude to the troubled times at the end of Sui Dynasty, and this army eventually became one of the executioners who destroyed Sui Dynasty. But it was not Zhai Rang who made Wagangjun famous, but Zhai Rang's successor, Shi Mi. It was Shi Biao who made Wagangjun's power reach its peak, and once became the most vocal among the heroes in the late Sui Dynasty. However, Shi Biao didn't win the world in the end. He was devastated when he defeated the queen. Later, he chose to surrender to the Tang Dynasty, but soon betrayed Li Yuan and died in Tang Jun. Shimei's failure was not only the inevitable development of history, but also closely related to his work in Wagangjun. If he hadn't launched a mutiny and killed Zhai Rang when he was in Wagangjun, it wouldn't have ended like this later.

Li Ji, formerly known as Xu Shiqi, was born in Lihu, Cao Zhou (now southeast of Dongming County, Heze City, Shandong Province). He joined the Wagang Army in his early years, then went down to the Tang Dynasty with Shi Mi, followed Li Shimin to pacify the four directions, northern expedition Xue Yantuo, and defeated East Turkistan and Goguryeo, and became one of the main commanders of the Tang Dynasty to expand its territory.

When Li Shimin launched the Xuanwumen rebellion, which side did the ministers have to take? However, the then Prime Minister Xu Maogong did not explicitly support Li Shimin, but Xu Maogong did not object. It can be said that he chose neutrality. Finally, Li Shimin succeeded in winning the position, although Xu Maogong was not immediately re-employed. But because of his talent, Li Shimin began to rely heavily on Xu Maogong.

In the thirteen years from 605 AD to 6 18 AD, he defeated Zhang Xutuo, Wang, and Yu, the famous soldiers of the Sui Dynasty. In the first year of Wude, Xu Shiqi and Li Mi went to the Tang Dynasty. Seal him as Lai, in charge of Shangzhou and Liyang. General Right Wuhou, to Lee. Well, he is thirty years old.

From 6 19 to the conquest of Koguryo in 668, Xu Maogong fought for the Tang Dynasty for nearly 50 years and made great contributions. He has participated in the battles of Hulaoguan, Fu Gongyou, East Turkistan, Xue Yantuo and Koguryo. After three emperors, Xu Maogong first unified the world for the Tang Dynasty, and then opened up territory for the Tang Dynasty. It can be said that he contributed a lot, and many top heroes in Lingyange can't compare with him.

In September 684, Xu Jingye and a group of people rose up and rebelled, transferred soldiers out of Yangzhou, and found a man who looked like Li Xian as an inside man. When Wang's "begging for Li" reached Beijing, Wu Zetian was furious and sent Li Xiaoyi to lead 300,000 troops to suppress the rebellion. At the same time, he wrote a letter to "chase the examiner of ancestor Li Zhi, send the coffin and restore the Xu family". According to people's records at that time, the tomb of the famous Tang Dynasty was completely destroyed and even burned to ashes.
