What should I do if I can't upload the itinerary code of Know-it-All Health Campus?

Refresh the network and upload again. The network condition is not very good or the mobile phone is stuck, which leads to several times before submission. Under normal circumstances, there is no card for health code and travel code, that is, the network conditions are not good, so you can refresh the network and upload it again. Know-it-all is a government service platform in Anhui Province, which can inquire and handle many businesses, including Ankang Code and travel itinerary Code.
