This is news to me. I had no idea that China had any ghost cities like this. The term doesn't really call to mind a newly built city actually. So why don't the government offer a year of free accommodation for teachers, medical professionals and families with young children. People can pay for their utilities and save their rent money for a year by which time they'll be attached to living there. Once there are available and functioning services more people will come to live there too. But I think that businesses have to be given an incentive to move their cooperate offices there so that workers will also move.
