@HarryChenPhD To hide the evidence of what exactly? I think I missed an important part of whatever it is your posting about and I'm curious.
@HarryChenPhD That seems a bit circular. If you have no sense of "what" they are covering up how do you know something is being covered up or that foreign powers are attempting to investigate, let alone being denied.
@freemo not sure exactly...the only thing that is certain is little info is getting out of china and they aren't allowing foreign powers in to investigate
