往北旳尽头海未眠向南旳天空云未散
[wăng bĕi dì jĭn tóu hăi wèi mián xiàng nán dì tiān kōng yún wèi sàn]
The phrase '往北旳尽头海未眠向南旳天空云未散' means 'North end of where the seas aren't asleep, southwards skies under clouds not dispersing'. The idiom portrays vastness beyond boundaries, longing for an end point that seems endless and an uncertainty in either direction; it's metaphorical language to express emotional distance and perpetual searching.
