Changsha is a city, but it won't work if it is too far from the workplace. Going back and forth for an hour or two, tossing and turning for four hours a day, makes people very tired.
It's better to settle down first and stay in a hostel or hotel. Generally, it will be cheaper around the school, and then interview to find a job. After the job is settled, rent a house nearby.
Just save money, be filial and take care of your own safety.
Good luck with everything.
