Excuse me, how much does this parking icon charge? Where can I pay? Thank you. The blue lines on the ground ?

This seems to be an internal parking lot, difficult to park.

Ms Li's answer is accurate. To add on, when the police conduct checks, they mainly look at the parking permit or the deadline for payment displayed on the front window of the vehicle (we had put the receipt in our pocket after deducting the payment, fortunately the police had not conducted a check during this period, otherwise our car would have been locked).
