清风归去
[qīng fēng guī qù]
Translated to English,'Return with the gentle breeze', it indicates that the person using it is tired of social engagements, eager to escape from the hustle and bustle back into a tranquil place for rest or seclusion. Also, in China, the word 'gentle breeze' is related to Taoist fairy stories - they say immortals travel riding clouds and mists, which is another possible reason why this name was adopted by some users.
