Does "emigration" mean "being an alternative traitor"?

That's not true. Don't want to go abroad unless you are particularly patriotic.

Everyone has motivation. Everyone wants to stay in a good place, and rural people want to go to the city. City people want to go to Beijing, and Beijingers want to go abroad. Because the conditions and welfare environment abroad are much better than at home, everyone wants to go abroad for their own happiness and future.
