Nanchang University can't punch in health cards.

Mobile phone network is not good. Nanchang University, founded in 1993, is a national "double first-class" plan to build a world-class discipline. Health card punching process is a process in today's school campus software. Students must clock in 14 days in a row and keep the green code, which meets the conditions for returning to school. If the user's network is not good, the health card punching service will not be able to punch in, and the user can change the mobile phone network to punch in again.
