Why is there a place called Yellow Flag, Blue Flag and White Flag in Inner Mongolia Autonomous Region? Tell me the names of the Eight Banners.

The Eight Banners System is a social organization system of military and civilian integration established by Taizu Nurhachi on the basis of Jurchen Niu Niu System in Qing Dynasty. In the twenty-ninth year of Wanli in the Ming Dynasty (160 1), four flags were built, namely yellow flag, blue flag, white flag and red flag. In the forty-three years of Wanli in the Ming Dynasty (16 15), four flags were added, called yellow flag, blue flag, red flag and white flag. Set 300 people as one Niu Niu, five Niu Niu as one Jia La, and five Jia La as an isolated mountain (the isolated mountain is the flag). Manchu people are divided into different flags according to the Eight Banners system, which are produced in peacetime and collected in wartime. When it was first built, it not only played an important role in the military, but also had administrative and production functions. After the reunification of the Qing Dynasty, Emperor Taizong and Huang Taiji established the Eight Banners of the Han Army and the Eight Banners of Mongolia in order to strengthen the shackles of the banners, enhance the military function of the Eight Banners system, expand military strength and win the hearts of the people. Each flag has military camp, pioneer camp, Xiao Qi camp, Jianrui camp and infantry battalion, and is in charge of guards, ladders and disposal. In addition, special camps such as Li Xiangying, Tiger Gun Camp, Fireware Camp and Ji Shen Camp were set up to practice wrestling, archery, tiger stabbing and gun testing. Because the emperors in the early Qing Dynasty attached great importance to practical skills such as guns and martial arts, the Eight Banners Army achieved brilliant results in pacifying San Francisco and incorporating Taiwan Province Province to resist Russian aggression. The Eight Banners are divided into Beijing battalion and garrison battalion. Elite is the general name of the Eight Banners Army guarding the capital, which consists of Lang Wei and Wei Bing. Someone who guards the royal family. Lang Wei must be a flag bearer with three flags inlaid with yellow and white, such as the meridian gate of the Forbidden City, the East-West Huamen Gate and the Shenwumen Gate.
