Why was Chifeng included in Inner Mongolia?

First of all, the name Tongliao appeared ten years ago and was changed from the original Zhelimu League. In other words, Tongliao just appeared ten years ago. After Japan's defeat, the East Mongolia Autonomous Government was established. From 65438 to 0949, the Inner Mongolia unification movement was formally incorporated into the Inner Mongolia Autonomous Region, and it has been under the jurisdiction of the Inner Mongolia Autonomous Region ever since. During the Cultural Revolution, the central government fought for power and profit, and in order to weaken Ulanhu's rights, five leagues (Xing 'an, Zhelimu, Hulunbeier, Alashan and Zhaowuda) were delineated in Inner Mongolia Autonomous Region. Zhelimu League was placed under the jurisdiction of Jilin Province for ten years, and was placed under the jurisdiction of Inner Mongolia after the Cultural Revolution. In other words, Zhelimu League has been managed by Jilin Province for less than ten years, so it is wrong to say that Tongliao has always belonged to Jilin. Secondly, there are indeed many fake Mongolians in Tongliao, but this phenomenon mostly exists in urban areas. The vast majority of Mongolians are purebred. Horqin belonged to Mongolia since ancient times, and the Han people in Tongliao basically came from "Broken East", but the second wave of immigrants moved in from the northeast, which brought the habits of the northeast people. At least half of the Mongolians in Tongliao are different from those in the northeast, while the Han people in the west of Inner Mongolia are mainly descendants of "going west". According to this person, they are all "Shanxi people" and the Mongolians in Tongliao are all locals. These so-called "Northeasters" are all outsiders and have never regarded Tongliao as their home. As a result, this absurd view that Tongliao belongs to the northeast has emerged. Tongliao is a city with strong Mongolian characteristics, from the beginning to the end.
