It's no problem to get on the expressway from Kunshan, but I'd better have the green code, and the travel itinerary code has no stars. All foreign (returning) Kunshan personnel within the administrative area of Suzhou should enter the "Lai" (returning) Kunming personnel independent declaration module through the Kunshan Citizen (Passepartout) app or scan the QR code.
You can also log in to the "Suzhou Tour" app, scan the QR code of the digital house number, and enter the "registration platform for people coming (returning) to the Soviet Union".
