Can Yunnan health code check the residence history?

Of course. "Yunnan Health Code" has been integrated with "Traffic Big Data Travel Card". Citizens only need to show their "Yunnan Health Code" and "Travel Card" at the same time to query their travel records, which is not only convenient for staff to query in one step, but also convenient for people to quickly open the "Traffic Big Data Travel Card" to query their travel information when entering and leaving public places such as railway stations, airports, medical institutions and shopping malls or taking buses and subways.
