Lyrics of Zhang Hongliang's should have known

How can you work hard? The result is just like this

How can it be a serious price? I'd rather throw it away

The stupidest thing is to do the same thing again and again

Every night as long as I think of it, I keep persuading myself

Every day I just wake up and forget yesterday's decision

It turns out that it's a life-long problem

You should have known, you should have known, you should have known

You should have known, you should have known, you should have known

（Music）

Stop asking where the source of distress is

Since then, I've been pretending to be stupid and happy

Desperate I will live in the hope of ignorance

Every night as long as I think of it, I keep persuading myself

Every day I just wake up and forget yesterday's decision

It turns out that it's a life-long problem

You should have known, you should have known, you should have known

You should have known, you should have known, you should have known

You should have known, you should have known, you should have known

It turned out that it was old and dead

Alternate torture of mind and body

I should have known
