I would suggest that you look at the region-level data for China, and just see if it looks anything like the European data.
For my money, I don't trust the US intelligence community but I still think that the Chinese numbers are somewhat implausible.
The charts show an identical dropoff in almost every region at the same time. We can see, from the European experience, that there's a lag between lockdown and case saturation. This does not appear in the Chinese data, which makes me somewhat sceptical.
Note that I'm not an epidemiologist, so it's possible that there's something else driving those numbers that I'm missing.
