There seems an invisible boundary in the sky, with clouds on both sides. Thick clouds covered the sun on one side and clouds dispersed to show azure sky on the other side.

Clouds in the sky present random irregular shapes.

Some citizens thought clouds were dispersed there, but they still thought it was miraculous that the boundary was so regular, so they took pictures with their phones. “Now ‘Chongqing blue’ is more and more common, and clouds and sunset glow also often appear.”

Such “magic” sight might be a local coincidence. Looking around, you would find that clouds present irregular shapes randomly in the sky. (Translated by Huang Juan, Fathom Language Limited)
