Wei Zi, the song they sang.

It's Heaven and Earth, and the lyrics are as follows:

Lyrics: Qiong Yao is composed by Xiao Jian.

Memories begin

How much tenderness is deeply planted

Hard journey, not easy to move.

Send this song far away.

How many past events

Everything is empty.

Countless connections

Into endless pain in my heart

Since you left.

The porcelain mandarin ducks on the roof were thickened by morning frost.

Endless nights

Jade cold, who is with * * *

Farewell reminder

Heaven and earth will meet.

Farewell, endless.

Why don't souls dream?

A person's love is as deep as the sea.

When will the beautiful scenery return?

Dream beyond dreams

Smile very gently, very gently.

Have met each other

In a daze, I had to guess.

Soul and dream

Come and go should be unimpeded.

Travel in the past

Half is weeds and half is moss.

Meng Shan is still there.

Only wandering alone

Three lives have an appointment

Wait, wait, wait.

A few phone calls

Come back, come back, look forward to coming back

Since you left.

The porcelain mandarin ducks on the roof were thickened by morning frost.

Endless nights

Jade cold, who is with * * *

Farewell reminder

Heaven and earth will meet.

Farewell, endless.

Why don't souls dream?

A person's love is as deep as the sea.

When will the beautiful scenery return?

Dream beyond dreams

Smile very gently, very gently.

Have met each other

In a daze, I had to guess.

Soul and dream

Come and go should be unimpeded.

Travel in the past

Half is weeds and half is moss.

Meng Shan is still there.

Only wandering alone

Three lives have an appointment

Wait, wait, wait.

A few phone calls

Come back, come back, look forward to coming back
