Can the American continent effectively and continuously attract a large number of immigrants?

It seems a bit dull and ignorant to ask who first discovered America. You might say, Columbus, the famous navigator, of course. Yes, it's Columbus, but that's the conclusion recognized by the whole world and recorded in books; But according to the latest historical discovery, it is proved that the earliest discovery of america in human history was not Columbus, but the ancient China people! They not only discovered the American continent first, but also immigrated to America in large numbers. A considerable number of Indians today are their descendants. Then why hasn't there been such a conclusion in the world for a long time? Is it because the self-promotion consciousness of ancient China people is not strong, or because Colombians have stronger self-promotion consciousness, better art and better self-promotion means? Maybe it's hard to find an answer to this question. In any case, China's discovery of America, the first man in ancient times, was not recognized by people, but Columbus was recognized, as evidenced by books! The experience of ancient China people may be a lesson of great practical significance to us-it is particularly important to pay attention to the consciousness and means of strategic self-improvement. In real life, if you are the "first person to discover America", have you ever thought about what you should do?
