Life is perpetual motion. You never know your friend who will be. I heard a friend current situation that he comes back from Shanghai to our hometown. I asked him the reason why returned. He felt very high pressure when lived in a big city. He could not stand the pressure for instance house price, living expense and over-stuffed trains or tubes. I know life is hard if you want to change. I don't know what's right thing but the currently one is the best way.
