1. Online payment: Jinjiang Library usually provides the function of online payment of late fees. You can log in to the library official website or use the library's App to find relevant options on the personal account page to pay.

2. Off-line payment: Some libraries also provide off-line payment of late fees. You can personally go to the service window or counter of the library to explain the situation to the staff and pay the fee.

Please note that due to library regulations, the specific payment methods may be different. I suggest you log in to official website of Jinjiang Library or consult their customer service department to find out the specific payment methods and requirements.
