Liaoshitong and Liaoshitong e-Dalian software nucleic acid data are universal. There are basically three types of codes currently used in Dalian. One is Liao Shi Tong Health Code, which is the most common. The health code interface can display 72-hour nucleic acid results. One is eDalian, which is the app of Dalian City. Nowadays, many places, including shopping malls, have changed the Liaoshitong health code to eDalian. In addition, eDalian displays a mode of adjusting the health code after scanning the code, which is not the mode of adjusting the health code of Liaoshitong. If you come to Dalian from other places, you need to scan e-Dalian registration before leaving the station. The third is the itinerary card, which is relatively small and is generally used for bathing and the like.
