China immigrants were the first.

China immigrants in history mainly went to Southeast Asia and the United States.

1, immigrated to Southeast Asia in the late Ming Dynasty. The war in the late Ming Dynasty led to a large number of immigrants to Southeast Asia, which reached its climax in the late Qing Dynasty. By 1905, the total number of overseas Chinese has reached 7 million. Until the low tide of several revolutions in modern times, China emigrated to Southeast Asia to escape political persecution. The refugees from Lower Nanyang come from most provinces and regions in China, but more than 95% are from Fujian and Guangdong. This is closely related to natural and human factors. Fujian and Guangdong provinces have twists and turns along the coast, and people learn from the sea, which is unmatched by mainland people; The two provinces are close to Nanyang, which is convenient to travel back and forth, and the road is close and economical. According to statistics, of Indonesia's 200 million population, about 10 million are Chinese; Malaysia has a population of 25 million and about 6 million Chinese. Thailand has a population of 65 million and about 20 million Chinese, accounting for nearly one third; Singapore has a population of more than 3 million, with Chinese accounting for 90%, which is the country with the highest proportion of overseas Chinese.

2. 1868, the United States and the Qing government signed the Sino-US Tianjin Expansion Treaty (referred to as the "Puanchen Treaty"). Article 5 stipulates that China people who wish to live permanently or become naturalized in the United States must listen to their freedom without hindrance. This opened the door for the United States to attract a large number of China workers to China. 185 1 year, there are 25,000 Chinese in California and 63,000 Chinese in the United States, all on the west coast. 1880,6,000 people arrived in the United States.
