Why do you choose to work far away?

My hometown is Qingdao, although it is not a big city, but because it is a central city, I have no reason to leave. The biggest advantage of a big city is its rich resources, which are incomparable in terms of employment opportunities, development space, medical resources and education level. Even children who grow up in big cities will have higher spirits, greater ideals, broader horizons and broader minds, which is why everyone yearns for big cities. However, the competition in big cities is quite fierce. It turns out that there are 1 junior college, 6 undergraduate courses and 3 master's degrees watching TV in Shenzhen street square, which also shows from one side that it is not easy for big cities to survive.
