The language advantage of mixed-race children is the easiest to understand, and the immersive language environment born in a family is incomparable to any language early education class. But the premise is that parents must often communicate with their children in their own mother tongue, otherwise the language advantage is limited. For example, if a couple comes from China and Greece and lives in Britain, they communicate with each other and their children in English, and the children go to a local school in Britain, then the children's knowledge of Chinese and Greek is quite limited. For another example, a couple is Guangzhou Renlang+Anhui daughter-in-law, and the husband indulges his wife, so they communicate with each other and communicate with their daughters in Mandarin. My daughter studied in a local school in Guangzhou and was admitted to a university in Hong Kong. As a result, before going to Hong Kong, she asked her father to teach her Cantonese. Nevertheless, the language conditions naturally brought by mixed-race families are incomparable to other mixed-race families, and its powerful language advantage is especially manifested in simultaneous interpretation. Their brains have been accustomed to the same meaning and two sets of statements since childhood, so with a little training, they can achieve professional simultaneous interpretation.

On the other hand, the language disadvantage of mixed-race children is not easy to understand. Yes, hybrids are born bilingual or even multilingual, but they spend less time immersed in a single language than non-hybrids, which leads to their lack of understanding of the political culture and tradition behind a language. For example, watching "in the name of people" at the same time makes it difficult for China people who grew up overseas to understand the political information conveyed by TV dramas and China's current cultural reality experience, even if their Chinese level is not bad.

What is even more difficult to understand is the identification of personal identity, "Jiang is still king". For example, in the first example mentioned in the first paragraph, he can consider himself an Englishman, but the local whites in Britain don't think so; It is even more unreliable to have parents who are from China or Greece. They will eventually become citizens of the earth, that is, when facing aliens, they can observe the personal identity of ordinary people. As a former British colony and now the China Special Administrative Region, Hong Kong people collectively have identity problems, so their undercover plays are particularly good, such as Infernal Affairs and Eavesdropping. And this identity problem will accompany them all their lives.

Knowing the language advantages and disadvantages of mixed-race children and learning the language of ordinary people, although we will encounter various problems and difficulties in learning foreign languages, we can at least overcome them through personal efforts. This is actually luck that many people don't understand, because no matter how hard we try, we can't solve other people's problems.
