The travel code keeps showing illegal entry.

The reason why travel itinerary shows illegal access is generally because the time of the system is not automatically corrected by the time of the mobile phone, which leads to the display of illegal access.

In this case, restart the applet, then check travel itinerary again, enter the mobile phone number of the real-name registration system, get the verification code, and then make an inquiry.
