往北的地方海未眠向南的地方云未散
[wăng bĕi de dì fāng hăi wèi mián xiàng nán de dì fāng yún wèi sàn]
'In the north, the sea remains sleepless, in the south, clouds still linger'. This poetic nickname evokes imagery of places or people being awake during deep hours or holding on to certain memories or emotions like drifting clouds without dissolving.
