Yang Jiajiang in the southwest of China is invincible in front of Mongolian soldiers. Why did it choose rebellion in the end?

Yang Jiajiang in the southwest has been guarding the southwest for more than 700 years since the late Tang Dynasty. In the face of the invincible Mongolian fighters, they are always loyal to the country. However, when Yang Yinglong was in the Ming Dynasty, he chose to defect because of his pride, and the name of loyalty in southwest Yang Jiajiang was destroyed.

Yang Jiajiang in the southwest, which has been guarding Bozhou, now Zunyi, is the longest buffer zone in the history of China. They defend the country's borders and produce heroes from generation to generation. Bozhou in Tang Dynasty was a military center in southwest China. Because of the remote terrain, the Tang Dynasty simply ignored it. Later, it was contracted to Yang Duan of Shanxi, who was responsible for the arrest. Later, Yang Duan and his uncle led nine children to form an army. After a hard battle, they finally recovered Bozhou and began Yang's governance of Bozhou.

Until the Song Dynasty, Yang Duan's descendants dedicated Bozhou to the Song Dynasty, and the Song Dynasty appointed Yang as the leader to continue guarding it. It became the Great Wall of Wan Li stationed in the southwest during the Song Dynasty. There were two Yang Jiajiang in the Song Dynasty, one in the south and the other in the north. Legend has it that young people in the north and the south are in the same strain, so young people in Bozhou have always been proud of their descendants. Later, when Mongolia invaded the Song Dynasty, Yang Jiajiang in Bozhou faced the Mongolian fighters, which was simply the Great Wall of Wan Li that the Mongols could not cross.

In the Ming Dynasty, Yang in the southwest belonged to the Ming Dynasty, hence the name of Miao chieftain. This legacy spread to Yang Yinglong from generation to generation, but he became the master of the last buffer region. Yang Yinglong made many contributions to the Ming Dynasty, but he was proud of himself, and his ambition swelled into rebellion. At that time, Chongqing was almost occupied because the Ming Dynasty was too busy to attend to it. Yang Yinglong couldn't stop the Ming army when it freed its hands to clean him up, and finally it ended in suicide, which led to the 700-year-old ruin of the buffer region.
