What is the difference between cultural adaptation and cross-cultural adaptation?

The first thing you need to know is what article you are in or what subject you are in.

I agree with the first answer, acculturation, which means the same as assimilation. Swallowed by a powerful civilization/mainstream culture. If the topic is about immigration, economic powers (America, France, etc. ) Generally, it will involve whether to abide by the principle of cultural diversity or choose to stick to their own inherent values (immigrants from foreign cultures need to give up their previous cultures and play according to other people's rules in the new cultural environment. Therefore, acculturation has cultural assimilation.

Cross-cultural adaptation only means that a person with different cultural backgrounds has adapted to a new culture in a new environment, which is a supplement to his own culture. There is no requirement to choose one.
