Traveling abroad, staying in the local area, and then being sent back to China, what happened overseas? What should I do if I return to China?

Those who stay abroad illegally will be repatriated free of charge. When you are caught by immigration, they will let you buy your own plane ticket, otherwise they will send you home. This involves the length of your limited employment time. If you go home at your own expense, the entry time is short. If they lock you up for 2-3 weeks first, they are talking about finding the cheapest flight to take you home, and the entry time is longer. After returning to China, you will have more human rights and no need to suffer unnecessary physical and mental trauma.
