What happens with the Chinese one child policy when twins are born? Do they still get fined or what?
The one child policy only really applies to cities outside the big cities nobody really cares, and tbh the one child policy is being relaxed as an experiment in a suburb of Shanghai somewhere. Due to the babyboomer demographic effect that almost all western nations are suffering right now. Anyway back on topic. If you are non Han Chinese nothing happens to you.
If you are Han Chinese and you have twins, nothing happens to you as it is one pregnancy and one birth and it is a circumstance which is beyond your control anyway. And tbh with the ever increasing cost of raising children in China two children is a big enough fine anyway so you won't get fined.
