The living environment in Tibet is extremely bad, but why don't local residents immigrate to the mainland as soon as possible?

Think about it. There are many backward provinces in China, such as Qinghai, Guizhou, Gansu and Hebei. Their people don't go to Shanghai or Beijing. There are many kinds of local protection, not only in local policies, but also in the unfriendly atmosphere of local residents themselves.

Rule number two

1 itself is so poor in Tibet that that person has no savings, can't afford a house, and has no buffer room.

Moreover, education is backward and you can't find a job abroad.

And they speak Tibetan, so they may not understand the language.

If you don't say that you are an immigrant or even discriminate, you should be careful.

And they may not know the mainland at all, and they don't know the goodness of the mainland.
