In fact, the tide of smuggling in the mainland began with the melee of warlords, which was the most serious during Japan's invasion of China. At that time, people who did not have Hong Kong resident cards (now called Hong Kong identity cards) were sent back to the mainland, and the total number of people who voluntarily returned to their hometowns reached several hundred thousand. At that time, the Japanese army killed all those who refused to obey orders, and then forced the citizens to exchange military tickets for human flesh. There are also many cases of rape.
