Because majority Chinese travellers are restricted from vacationing abroad, cabin fever pent up domestic travelling have been on the rise. All of Mainland, not just within Yunnan.
Chinese citizens are also required to use this new movement tracker at various entry points of tourist destinations outside Kunming. I've witnessed this first hand, just not at Kunming Changshui Airport's domestic departure for Chinese citizens
For foreigners with language barrier, airline check-in attendants may guide you through the mini program registration process after WeChat circular barcode is scanned. They'd actually take your phone to make sure both greens for health code and movement tracker are not screenshots.
For foreigners flying out of Kunming Airport, apart from the usual scanning of health code (still active btw), another updated version which tracks your movement needs to be scanned and presented to flight check-in attendant for verification.
It is called "动态行程卡" and proves you haven't left Yunnan for example (or country) within last 14 days. If the case the app interface will be displayed as green like the health code.
A bar code will be presented to be scanned.
Or search for it on WeChat as "通信大数据行程卡." SMS verification needed to login.
Not sure if applicable for travellers outside Yunnan across Mainland. Hunch is yes.
