Who has heard a song sung by Wu Bai? Lyrics are the classic lines in the movie A Chinese Odyssey. What's the name of this song?

There are two singers, one is Andy Lau and the other is Wu Bai. Two people are singing two completely different songs, but they have the same title!

-Lyrics:

There was once a sincere love in front of me.

Do not know how to cherish, turn a blind eye.

When everything was lost, I regretted it.

The most painful thing in the world is this.

If god can give me a second chance.

I'll tell her I love you.

If you have to add a deadline to this love

I hope it's ten thousand years.

There was once a sincere love in front of me.

Do not know how to cherish, turn a blind eye.

When everything was lost, I regretted it.

The most painful thing in the world is this.

If god can give me a second chance.

I'll tell her I love you.

If you have to add a deadline to this love

I hope it's ten thousand years.
