Why are the clouds so low in Guangzhou?

The height of clouds depends on the density of the atmosphere, that is, the pressure. High pressure represents high clouds and low pressure represents low clouds. This similarity can be explained by the principle of buoyancy: when the cloud is light and the air pressure is low, the cloud can be very low, such as the Qinghai-Tibet Plateau. When the air pressure is low, the clouds will fall very low. For example, before it rains, it rains in Guangzhou, so the clouds are relatively low.
