Mobile phone printing admission ticket can't see the verification code.

There are too many people logging in online. When printing the admission ticket, you will encounter the situation that you can't log in or don't display the verification code after entering. This situation is because there are too many online loggers and the system is at its peak. If you need to log in again or avoid rush hour, print the admission ticket at a time when there are few people, as long as it can be printed within the specified time. If it still doesn't work, you can try another browser. Sometimes the browser version is too low, which will make it impossible to open the web page.
