The official story now seems to be Chinese bio-weapon....
Yeah, and being spread by no less than former heads of the CIA and MI6, Mike Pompeo and Richard Dearlove.
The articles you linked don't actually say the idea that a "Chinese bio-weapon" is the "official story."
Richard Dearlove was the head of MI6 from 1999 to 2004. He offers his personal belief that the virus is a made in a laboratory. This goes against the British intelligence community, which has declared it not man-made. He's careful not to say it's a "bio-weapon":
"I am not saying anything other than it was the result of an accident and that the virus is the consequence of gain-of-function experiments that were being conducted in Wuhan, which I don't think are particularly sinister."
The article also says the US intelligence community
doesn't think a "Chinese bio-weapon" is the most likely explanation:
The US intelligence community took the unusual step of releasing a statement to say it concurred with the consensus view that the disease was not man-made, but spies are investigating whether the virus might have been held in a laboratory and leaked accidentally.
Since the virus lacks markers that indicate that it was created in a laboratory, most scientists also consider "Chinese bio-weapon" as the
unlikely explanation for the virus.
That's not to say that it's impossible that the virus is man-made, or that it can't be part of a Chinese bio-weapon program.
But the article doesn't support the conclusion that "Chinese bio-weapon" is the "official story" for the virus. In fact, it says the opposite.
The second article you cite gives a long list of lies that China gave about the Corona virus.
However, nowhere does it suggest that virus is a "Chinese bio-weapon".
That said (and most importantly): Thumbs up on looking out for others! Stay safe.
