"In meteorology, there is a phenomenon called smog with the symbol ∞. Haze is also a slight dusty weather, but it is smaller than dust particles, similar to fog. Fog is mainly composed of small droplets, while haze is mainly composed of small solid particles and also contains some small droplets, which are called aerosol particles in meteorology. When there is haze, a large number of aerosol particles scatter sunlight, the sky is pale yellow, and the fog is mostly milky white. This symbol seems to describe the turbidity of the atmosphere and its long-term persistence. "
