oh the eye boggling thing... In a nutshell, that is the Feb research from the South China University of Technology that got under the CCP's skin. Basically says: likely didn't come from wet market and likely came from a lab where an engineered chimera virus from bats was "residing". (The research our NIH was funding back in 2015 etc.)
In oversimplified kindergarten language, a chimera is when you put a frog with a dog and get a fro-dog.
