Back in Feb 2020, a rumor circulating on Chinese social media said that there was another lab in the city near the market, which was a competitor to the lab of Wuhan Institute of Virology that is most widely mentioned, under the umbrella of a university of agriculture/forestry/geology (I don't remember the exact details).
I am not sure about the validity of the rumor, though.
