What is the difference between Hong Kong, Macao and overseas representatives now and before?

Internal differences are becoming more and more obvious, and identity changes and diversification. According to the query, People's Daily Online shows that.

1. The internal differences are becoming more and more obvious: although tens of millions of overseas Chinese have the same ethnic background, they are not a highly identical group, but have various differences, and this difference is becoming more and more obvious. This difference includes the differences of birth, residence, language, class and generation.

2. Change and diversification of identity: the identity of international immigrants is very complicated. It includes not only the identity of the country of origin, but also the identity of the country of residence, including national identity, political identity, cultural identity, ethnic identity and other multi-level identities, involving both self-identity and other identities.
