Well you only need the light when it's burning low
残灯淡影思春曦
Only miss the sun when it starts to snow
唯见飞雪慕暖阳
Only know you love her when you let her go
昔人已去知情深
Only know you've been high when you're feeling low
卧心追念峥嵘日
Only hate the road when you’re missing home
乡愁暗涌恨旅遥
Only know you love her when you let her go And you let her go
人去徒留空喜欢
Staring at the bottom of your glass
醉然端目杯中浅
Hoping one day you'll make a dream last
盼君初心久未变
But dreams come slow and they go so fast
匆匆梦来匆匆去
You see her when you close your eyes
魂绕梦萦映眼帘
