Colorful clouds appear over Huize, Yunnan

Colorful clouds appeared over Huize County, Southwest China's Yunnan Province, on Thursday.

The clouds, called "seven-colored auspicious clouds", were seen not long after the sunrise and continued until noon, attracting passers-by.

It is said that the phenomenon is called "solar corona", which is the diffraction of sunlight that occurs after refraction from the sun.
