I really dont understand how there's only one visual source for this out of "thousands of witnesses". Has anyone found even ONE still that wasnt from this video or any other video altogether?

I'm finding it nearly impossible to believe that literally no one else has posted their own pics or videoes. Was this in a part of China where not many people have cameras or cell phones or something? Its enormously unlikely that this really happened if only one person out of thousands of witnesses decided this needed to be uploaded for the world to see.
