The relationship between blacks and whites is getting better and better. Many black people immigrated from Europe and America. Why?

In the United States, there will still be black areas that white people dare not enter ~ Now the relationship has indeed eased, but it is not as perfect as in the movie, and there has also been a crack in the relationship between black people and white people ~ It's just that this crack has not been stimulated more strongly ~ The reason why yellow people don't like white people and black people is that they are too hard, and they will grab business wherever they go, making other people's business very poor. Of course, they don't.
