Why do health code pandas run around?

Traveling panda. On June 4th, the panda officially logged into "Sichuan Tianfu Health Code". Because it is a traveling panda, it travels everywhere. After all doses of COVID-19 vaccination, the user will display a panda head after his name. At the same time, he will randomly get a cute panda from different tourist landmarks in Sichuan Province, open the "green code" and instantly have the pleasure of "opening the blind box".
