Can WeChat apply for multiple health codes?

I can't. A mobile phone can apply for one WeChat, and if there are two WeChat, you can apply for two. The "health code" is based on real data, which can be generated by citizens or people who have returned to work on their own online declaration and background audit.

Once you scan the health code software with your mobile phone, it will immediately retrieve your mobile phone usage, vehicle usage and code scanning shopping, get your action trajectory and activity area some time ago, and then look at the coincidence degree of your action trajectory and activity area with confirmed cases or suspected cases, so as to judge whether you have been exposed to confirmed cases or suspected cases.

Green code: you can pass.

Code yellow: implementation 7? The sky is isolated. Seven times in a few days, the health clock is normal and turns into a green code.

Red team: implement 14? The sky is isolated. Continuous 14? The health clock is normal, turn to green code.
