Guanzhong Immigrants in Warring States Period

Zhao Kuo's descendants changed their surname to Ma, not because it was ordered by Qin Shihuang. However, because their ancestor Zhao She was named Ma Fujun by King Wuling of Zhao at that time because of his exploits, and his fief was called Ma Fu, he was buried in his fief after his death, so his descendants began to take Ma Fu as their surname. Later, for brevity, the word "Ma Fu" was removed and became Ma Shi.

Then the Qin Dynasty unified the whole country, and then when Qin Shihuang was in power, he planned to carry out a large-scale migration, so that all the rich people in the world moved to Xianyang. Qin Shihuang moved the descendants of Zhao She and Ma's family from Handan to Xianyang, which was a historic migration of Ma's family. Moreover, in order to appease the Ma family, Qin Shihuang also named Ma Xing, the master at that time, as an ambassador.

In fact, Qin Shihuang did this not because he attached great importance to the Ma family, but because he unified the world at that time. Afraid of some giants and clans in the East, they secretly colluded and wanted to overthrow his rule, so they planned and implemented such a large-scale migration, so that after they moved to Guanzhong, it was convenient to monitor them too much and prevent them from getting close. So as to consolidate their position.

There are descendants of Zhao Kuo, because Qin Jun slaughtered the descendants of Zhao She when attacking Zhao, but some of them survived, most of them fled to other places, such as Shaanxi and Henan, and settled down there, so they gradually developed into local aristocratic families, so these people were considered as descendants of Zhao Kuo.
