海是没有心的城心是没有城的海
[hăi shì méi yŏu xīn de chéng xīn shì méi yŏu chéng de hăi]
This internet name expresses the loneliness and vastness of the ocean. The sea represents freedom, boundless like a city without boundaries; conversely, a heart can be boundless but it can't contain its vastness like the sea. This reflects emotions and thoughts of longing and solitude.
