It is the theme song of the movie Old Things in the South of the City.

The lyrics are as follows

Changting Waigudaobian

The grass is blue and the sky is blue.

The evening breeze helps the willow flute sound residual.

Sunset mountain outside the mountain

Corner of heaven and earth

Good friends are half separated.

A pot of muddy wine is perfect.

Say goodbye to Meng Han tonight.

Changting Waigudaobian

The grass is blue and the sky is blue.

The evening breeze helps the willow flute sound residual.

Corner of heaven and earth

Good friends are half separated.

A pot of muddy wine is perfect.

Say goodbye to Meng Han tonight.

Sunset mountain outside the mountain

Corner of heaven and earth

Good friends are half separated.

A pot of muddy wine is perfect.

Say goodbye to Meng Han tonight.

Changting Waigudaobian

The grass is blue and the sky is blue.

The evening breeze helps the willow flute sound residual.

Sunset mountain outside the mountain
