You can't.

The Chinese Government already deployed Health Code, which pulls data from cell towers to check for cross paths with confirmed or suspected patients, and shows on screen as green, yellow or red colored QR code.

I agree -- I would say the government should recognize the utility of the idea and request an emergency technical team from both Apple and Google to join up in a public-health emergency response consortium (to ensure interoperability) and brainstorm this idea. And Microsoft too, if they are still making windows phones.

I'm sorry but are you literally asking governments to cooperate with Apple and Google to backdoor all of our devices or do so and bully the population into submitting their data? There's a point where we need to talk about trade-offs between tracking potential disease contacts and what this does to our society. China isn't supposed to be a role model in this regard people.
