Rules about maternity leave in China (Shenzhen)

Hello everyone. I have been in Shenzhen for about 3 months now. Just after accepting to come out here, I became pregnant and our baby is due in October. I need to settle the maternity leave with the company I work for here, so I am wondering if any one knows the "normal" length of maternity leave in China/Shenzhen?
Any other advice regarding living with an infant in China is also appreciated (will go back to Denmark for delivery). My boyfriend is from Tanzania and still in university there, so it will be a while before he can join our little family here.

Thanks :)
Anne
