These ghost cities start that way, but they all end up being populated, and as soon as the flood gates open, they fill up fast. It just takes certain factors reaching critical mass to push them from the 'No one is living there' to 'Everyone is moving in and filling the entire place up'

As usual, the initial settling is largely happening due to the Chinese government applying artificial levers to get people to move there, but that's a tactic they've used successfully on a lot of these "ghost towns"
