24h Open station of the public bikes in Hangzhou?

As far as I know, there are about 55 points opening 24 hours in the whole city.
I am not very clear where you are, so it is hard to tell you the detail information. Generally speaking, at Wushan Squre, Longxiang Bridge, No. 7, Meizheng Road, Santang Central Station, Wulin Square, No. 22, North Changjiang Road and some other places open 24 hours.

Thank you so much! Is there any web site where I can see all the spots ? And do you Know what happens when I return a bike after closing time (9pm)?

I live near Fuxing bridge...
