Is it better to immigrate to Korea than to stay in Shanghai?

Korea is not so good, not so good on TV, and most people are quite poor. And fruit is super expensive. My relatives went and the food was not used to it. They eat fried rice every day, which is very expensive. They spend all their wages and don't save any money. And Koreans are quite exclusive. Work is hard, too. It's normal to get off work at 8 o'clock there. Let's get off work here at 6 o'clock.
