Public bicycle parking spaces are full, how can users return them?

The solution is as follows: lock your car on a post and people can go, or stay after registration. Find an empty post that can be returned, and then call this number to let the staff cancel it. Then return the car according to the normal procedure, and there is no charge during the period. If you lock your car on a post and leave, be sure to return it to an empty place after use, otherwise no one else will use it. You can find other bicycle parking spots nearby.
