What if I go outside in Longyan and can't come back? ...

You are too dependent on your partner. Since all your former companions are studying, you should find a new one. You have your life circle and they have their life circle. As for finding a job for seven hours a day in Longyan, to be honest, unless it is part-time. It takes six hours to work the night shift at KTV, and it's also a part-time job. It takes more than two hours to work full time. Actually, it's the same everywhere. If you stay in one place for a long time, you won't feel fun. It's easier to make friends outside, but you have to keep your eyes open. Because there are too many bitches out there ... Be careful. Of course, don't be too introverted. Friends should be made, but not the kind of friends who have a heart-to-heart relationship. It's up to you.
