Could you share some sources for that assertion?
Why would you search Google Scholar for the claim "Chinese authorities censored doctors trying to warn the population [about COVID]"?
In general, it's not a good look to go around asking for sources for facts that are very well known.
I'm also curious as to why you thought that this was "very well known," however. Could you elaborate on how you determine which set of facts can be selected to be well known, and which set cannot?
