Why was the daytime flight from Guangzhou to Nanyang cancelled?

The reason for the cancellation of daytime flights from Guangzhou to Nanyang is that before take-off, the latest meteorological information may have detected thunderstorm weather or haze weather, and the plane can't operate in thunderstorm weather and haze weather, so the flight will be cancelled and the flight will return to normal after the thunderstorm weather has passed.
