China wouldn't be QUITE back to normal, just...closer. They're an authoritarian state that used it's power to the fullest to go after the virus. We only speculate about such things in movies, they were willing to go full on zombie apocalypse lockdown over COVID. That's...exceptional. Therefore, I'm not too surprised that the results were also exceptional. Still, they still seem pretty lockdown twitchy, like they're ready to lock down anybody and anywhere at a moments cough.
