It seems China's handling Covid rather well. The key to that, lies, I suppose. in its people's discipline.
We all know that without discipline nothing good and lasting can be achieved ; not in schools, not in the army, not at work...nowhere.
The disciplined population, helps China successfully practice the strategy of zero tolerance towards the virus.
This strategy includes: mass testing, quarantine, surveillance, localized lock-downs, and more. A sporadic outbreak is immediately dealt with lock-down to prevent further spreading of the virus. China' s trying to achieve zero infection while elsewhere, in the Western world, people are getting used 'to live with the virus', vaccines and boosters.
(The Chinese are not too confident about the effectiveness of the vaccines to prevent infection. They believe, as we do, vaccinated people might still contract covid, but perhaps won't have to go to hospital).
The zero tolerance policy is also part of the Chinese narrative to claim superiority of their system (political, medical, social etc...) over the West. They would like us to believe through the pandemic that China could "conquer" the West with no tanks, rockets, or the nuke - but with a tiny virus.
After all, the virus started its 'activity' in one of China's towns, Wuhan, and according to one of the theories - in the town's laboratory - specialized in coronas, and which belongs to the Wuhan Institute of Virology. The lab, a 40 minutes drive from the Huan Market where the first infection was spotted, could have been engaged in a possible testing of a biological weapon . So who knows?!
