Different from the new immigrants who came to Chinese mainland to study, work and live in Korea after the establishment of diplomatic relations between China and South Korea (200,000,160,000 Korean in China and 40,000 Han in China).

Today, there are about 23,000 people in South Korea and 22 133 people in North Korea, accounting for 0.06% of the total population of 71858,500, making it the second largest ethnic group after the Korean people. Most Chinese in Korea gather in Incheon, followed by Busan and Seoul.

More than 95% of Koreans come from Shandong, and most of them come from Yantai, Qingdao and Weihai. All over the world, Chinese and overseas Chinese have made many economic achievements, but the overseas Chinese economy in Korea is difficult to develop. The reason is that the Korean government has promulgated many laws to exclude Chinese businessmen in the past and restricted the economic activities of overseas Chinese in many aspects. At first, there were more than100000 overseas Chinese, and then it gradually decreased to more than 20000. Most of them immigrated to the United States and Canada, and some of them went to Taiwan Province Province and stayed in Korea. Except for those who have achieved great economic success, their lives are not very good. With South Korea actively exploring the China market, many overseas Chinese have benefited from it, and some of them have served as tour guides or translators.
