I can tell you the most of the Chinese who went to Japan more than 30years ago went to work as gangsters and illegal workers,and only a few were genuine international student. a bunch of so called shanghai gang and fuqing gangs gather in Kabukicho, shinjuku, shinokubo , ikebukuro and ueno. some private casino ,selling counterfeit international calling card and using counterfeit pachinko cards to make money, now, they have been upgraded to citizens after staying for a long time. naturally , feel superior to others......🤣🤣😂
