Is that Japanese Li Zhongcheng Korean? Immigrate to Japan

Yes! Similar to North Korean player Zheng Dashi. Because of historical problems, North Korea has been a Japanese colony for too long. There are too many Koreans living in Japan. Japan lost its colonial rights after World War II. North Koreans stranded in Japan are voluntary. Many people choose to return to China (certainly not sure whether it is South Korea or North Korea). Some people choose to stay. Japanese law allows these adults to choose their own nationality, and of course it also affirms each other's right of residence in Japan. So we see players like Zheng Dashi who wear Korean jerseys but live in Japan. In the same way, many Koreans directly chose Japanese nationality. Therefore, it is reasonable for them to go out in Japanese uniforms today.
