没有伱那一片黯然天空
[méi yŏu nĭ nèi yī piàn àn rán tiān kōng]
Translation is 'Without you, that piece of sky turns dim.' This signifies feeling sorrow or bleakness due to absence of someone loved. The sentiment conveys a sense of longing and how missing someone can darken your day like clouds overcast a bright blue sky.
