What is the largest immigrant population in the world?

First of all, I want to say that from the perspective of global development, it is like this: to answer this question with modern science, western industrial civilization originated from the European coast-Britain; The origin of the British is Celtic and Germanic, two of the three major races in Europe, with Germanic as the main body; Geographically speaking, Britain can find racial forms including Spain, Portugal, France, the Netherlands and Northern Europe. Overseas British immigrants are the most in the world, which also shows that overseas European coastal immigrants are the most; The same is true in Asia, except that the entire coast of the Asian continent is surrounded by Asian islands;

The coastal areas of China belong to four major ethnic groups: Jiaodong Peninsula and Liaodong Peninsula, Jianghuai Region and Qinling Region, the coastal areas between the Yangtze River and the Pearl River, and the coastal areas between the Vietnamese Pearl River and the Red River. From a global perspective, the overseas population of Liaodong Peninsula in Jiaodong is scattered; Jianghuai area is mostly in Japan; The population in the area between the Yangtze River and the Pearl River is concentrated in Southeast Asia, South Africa (Fujian), Brazil (Fujian) and Western Europe (Zhejiang). The last one is the Chinese subject in North America and Central America;

Look at Asian geography again: the Asian continent is divided into East Asia and Southeast Asia, and East Asia includes Mongolia, Siberia, Korean Peninsula and China; Southeast Asia includes Tibet (geographically speaking, non-political) and Indochina Peninsula; From north to south, the islands are: Japanese Islands, Taiwan Province Island, Philippine Islands, Borneo Island, Java Island and Sumatra Island; Among them, it is recognized that the earliest human being is a little black man from South Asia, but the main ethnic group is very complicated;

Of course, the main ethnic groups on the island also come from the Asian continent: most of the ancestors of Sumatra and Java came from the western Indochina Peninsula (the extension of the Himalayas) adjacent to India; The peoples of the Japanese archipelago are the Korean Peninsula and the Jianghuai area north of the Yangtze River in China. You can know the origin of Japanese by listening to Korean and talking to South Korea. Of course, the main body is the Korean Peninsula (otherwise the relationship with China will not be like this); The main body of Taiwan Province Island is Minnan area of Fujian; In terms of plates, the Philippine Islands were formed by the extension of the Korean Peninsula and the West Japanese Plate and the extension and impact of the land plate along the southwest coast of China, so it can be imagined where the main body of the Philippines came from: the Korean Peninsula system and the southwest coastal system of China, and now the main body is the Korean Peninsula system; The main body of Borneo is unknown (but there are many Hakka immigrants in Fujian and Guangdong);

So, what do you think are the similarities between Filipino bamboo dance and ethnic bamboo dance? Hainan, Guangxi and Guangdong, of course. In addition, in the United States, Filipinos are the most populous Asian except Chinese. ......
