What is "don't go out at sunrise, thousands of miles after sunset"?

If you don't go out at sunrise and travel thousands of miles at sunset, it means that if you get up in the morning and see a sunrise on the horizon, the weather may be bad today; If you see the sunset glow on the horizon at night, it is likely to be sunny the next day.

"Don't go out at sunrise, but travel thousands of miles at sunset", a proverb, means that there is a red glow in the morning, which indicates that it is raining and it is not suitable to go out; Red clouds appear in the evening, indicating that it will be fine and you can travel far.

Generally speaking, in summer morning, the low-altitude air is stable and there is less dust. If there is a sunrise, it means that there are many water drops and clouds in the eastern low altitude. As the sun rises, the thermal convection gradually develops to the flat ground, and the clouds will gradually become dense, so there may be bad weather such as windy and rainy.

At night, due to the sunshine heating in one day, the temperature is high, and there is less water in the low-altitude atmosphere. However, due to the weakening of convection, dust may be concentrated in the lower level. Sunset is mainly caused by the scattering of sunlight by dry particles such as dust, so if there is a sunset at night, it proves that the weather the next day is generally good and suitable for travel.
