Why do blacks bully Chinese in America, but dare not bully Koreans?

In the United States, no one knows that you are Korean Chinese, and even Asians bully you, but the Chinese community is really weak. Why? You have to look at the time when these people go to America. Nowadays, many China people come from the Qing Dynasty and the Republic of China, when China's national strength was in extreme decline. These people are still very conservative and dare not speak out when they are bullied. On the contrary, it discriminates against new immigrants who have passed after the domestic strength is strong, so even if China's national strength is stronger than before, the overseas Chinese community is still weak. This situation will take at least two or three generations to change. In fact, it was only after these Qing veterans left.
