China had to slaughter and dispose of millions of pigs up to november 2019. There were stories of drones being used to infect pig farms through the summer to drive up pork prices. Odds are that this was covered up so much that when it hit the breaking point, people blamed the lab, even though wuhan is down stream from farm lands.
Realistically they were over taxed and they missed the SARs outbreak. Probably why they are using draconian methods still and welding people into their homes, to make up for their lax action.
