Read "Huo Shao Yun" and talk about what Huo Shao Yun refers to?

When the sun just comes out, or when the sun is about to set in the evening, the clouds in the sky are often bright red, like fire, called Huoshaoyun, also called morning glow and sunset glow.

Huoshaoyun is the red cloud that appears at sunrise or sunset. Fire clouds belong to the category of low clouds and are one of the phenomena of atmospheric changes. It often appears in the summer, especially around sunset after a thunderstorm, in the western part of the sky. Due to the strong evaporation on the ground, the updraft in the atmosphere has a greater effect, making the shape of the fire cloud ever-changing.
