What does Yun Guan mean?

Yun Guan means to guess whether it is raining or sunny by observing the clouds.

Understanding the astronomical phenomena in Yun Guan is actually observing the changes of celestial bodies, constellations and clouds in the sky. The ancients could predict what would happen by observing the changes of stars in the sky. Of course, not everyone can observe the changes of stars, only astronomers with this knowledge can see them.

The ancients not only knew the weather according to experience, but also drew the weather cloud map. As early as Yao Di's time, full-time civil servants were set up to be responsible for "observing images and timing". There have been weather phenomena such as wind, rain, snow, clouds, rainbow and thunder in Oracle Bone Inscriptions unearthed in China, and divination has also been used to predict weather information.

From the Qin Dynasty to the Han Dynasty, it is not difficult to find various cloud pictures recorded by the people. There is Guan Yu in Han Shu's Records of Literature and Art, and Dazzling Clouds in the Sun and Moon in the Song Dynasty. It can be understood as predicting and inferring the future weather evolution by observing the amount of clouds, the shape characteristics of clouds and the changes of astronomical phenomena.
