Why can't Chengdu Giant Panda Base buy tickets in advance?

The reasons why Chengdu Giant Panda Base can't make an appointment to purchase tickets are as follows:

1. The number of reserved votes has reached the upper limit, that is, it is sold out or cannot meet the reservation conditions. Suggest another time or use other tickets.

2. If the system is busy or under maintenance, you can wait a while before trying to buy tickets.

3. Network problems. If 4G can't make an appointment, you can try to switch to 3G or use other network environments.

4. If the user's own equipment or network is unstable, he can change the equipment or use other network environment to make an appointment.

5. Too many visitors will cause the system to crash or fail to connect. You can try again later or contact the relevant staff for help.

These are some reasons that may lead to the failure of booking tickets at Chengdu Giant Panda Base. If you still can't solve the problem, it is recommended to contact the scenic spot staff directly for help.
