Great question. To be honest, I was the biggest China skeptic of all. If you read the first 20 pages of this thread, you'll see many posts where I slam China numbers, disparage them for being inaccurate and question what the reality of this virus is. In fact, I update numbers every night, and I don't include the numbers from China. The reason my numbers don't include China (all the main number counting websites INCLUDING the John Hopkins website DO include China) is because I didn't believe them.
All that changed when the WHO went to China and opened their doors. Their "scientific backing" of the numbers changed my tune.

The above has been my definitive "bible" regarding this virus. Once I read it, I was astounded at how detailed it was.
This was released on Feb 24th I think. It was released at a time when China was on the backside of their epidemic. In the 5-6 weeks since that time, everything that we've seen points to China having gotten past the problem. So if they had a problem, and they defeated the problem, shouldn't we listen to them?
Then when you read the experts, they always talk about China and what China did. The NYT has frequently had podcasts where experts discuss the quarantine methods that China used and talk about why they were successful.
I am 100% convinced that China knew within a 95% =/- ratio exactly how many cases they had, because they defeated the virus in a MUCH quicker way than any other country has.
So were they lying in the info they released to the rest of the world? Possibly. But why? And why are their numbers used by so many scientists?
