What's the difference between relocation and immigration?

Relocation: Relocation to other places due to the demolition or renovation of the original buildings, and mobilization and relocation of the original residents in the development area due to development needs.

Immigrants: Immigrants are individuals or groups who have moved from one country or region to another for a long time, engaged in economic activities to make a living in the place where they moved, and were given local social obligations.

The migration movement is essentially different from the large-scale population migration caused by military conquest and invasion. It is a kind of national expansion activity and economic expansion form in the process of human development.

One is because of architecture, and the other is because of the needs of regional development.

In fact, there is a big point between relocation and immigration, that is, to paraphrase an ordinary person, whether people will immigrate with human communicative competence, that is, the improvement of intercultural communicative competence mainly comes from teaching Chinese as a foreign language.
