Seems that you just don't believe the other side has done some investigation and therefore did not search for it. I'm not saying that either incident is fake but you've just proved my point of view.
But that is not relevant to point that Chinese state media (which is in a way all their media, like becoming in Russia now) is wrong and lies regularly but will never undermine the cult of personality at the top of the government that owns it by admitting the lies.
To deny that you need to go all tinfoil on me and say most instances where they lied is made up by the West. Like idk Tiananmen didn't happen or whatever. If you believe that then sure.
On that front China has a far worse track record and institutions that uses evidence based truth telling.
