Why not move the aborigines out of Beijing?

The true aborigines in Beijing are the Khitans, who have long since disappeared. Even the flag bearer who rode from Manchuria (Northeast China) in his early years was actually a foreigner (Manchu indigenous) who came to Beijing. Now they are born and raised in Beijing, and almost all of them are descendants or children of previous generations of immigrants. Beijing is only their birthplace, and their native place is other places or provinces, not to mention "aborigines" or "aborigines". In fact, it should belong to the "previous generation of foreigners", but every family comes. People who have the ability to survive in Beijing will live here, but if they are unable or under too much pressure, they will naturally move to other places. A large number of so-called "Beijingers" (old outsiders) who came several generations earlier have already moved outside the Fifth Ring Road such as Tiantongyuan and Huilongguan (places under the jurisdiction of Hebei 58 years ago), and too many people have also moved to Yanjiao, Gu 'an, Zhuozhou and Langfang in Hebei ~ ~ ~
