The username translates as 'The Fog Over the Southern Sea Hasn't Dispersed; The Clouds in the Northern Sky Have Not Fallen Asleep.' This is a poetic way to depict lingering worries or continuous uncertainty. South and north here may represent different aspects of the individual's world, with fog and un-slept clouds signifying unresolving issues.
