Where did the Mongolians in Song Jia Town migrate from?

In the Mongolian villages of Chaobei Town, Song Jia Town and Laozhuang Township in zhenping county, there is a legend that the ancestors of Chaobei Mongolians were Tiemuhuaer, the fourth son of Yuan Shundi, the last emperor of the Yuan Dynasty, who came to Chaobei to live in seclusion from Dadu (now Beijing) after the demise of the Yuan Dynasty. This legend has also been recognized by relevant scholars. They believe that the Mongols living in Chaobei Town, zhenping county, Nanyang area and the Mongols scattered there are all descendants of Yuan officials who lived in seclusion at the end of Yuan Dynasty. On this point, there is a clear record in this Mongolian genealogy: "In the Yuan Dynasty, during the reign of Emperor Wenzong, the emperor followed the royal pole, and the master crossed the river with Heyang, taking Taiping Road to force Yanjing, and Yuan Di rushed to Yingchang, so he moved." Seeing the vicissitudes of life, the public took care of themselves, traveled to the north of Hebei, took Wan Li Road, diverted the Yangtze River to the left, and crossed Henan. The ancestors' experience was exhausted. "From the above genealogy, we can see that their ancestor Temuwar was handed down from the fourth generation of Chaopi, and their ancestors had no real names, namely" Raul ","Da Lao "as the second ancestor, Gui Wang as the third ancestor and Wang Zongxiang as the fourth ancestor. Their tombstones only have the words "the tomb of princes", and no names appear. Their names only appear on the tombstone of the fifth ancestor, Wang Dongxi being the fifth ancestor.

A native of Song Jia Town, Mongolian, whose ancestor is Temuwar, came from Dadu (Beijing) and went to Chaopi first. Later generations branch to Song Jia Town, with a straight line distance of 12 km.
