What is the name of the song about Tianmen Mountain that Geng Hao and Hao Yi sang on stage when they arrived at Tianmen Mountain?

Avatar and the Loser Man

Lyrics: Dong Dong Dong

Sung by: Xu Hepin

You're from Pandora's Star

I'm from Tianmen Mountain

You're blue in green

I'm yellow in color

Meeting with you in the mountain fortress

You've got to be careful

There can be real love between Avatar and the Loser Man

And there can also be real love between them. I'm a yellow loser

There's love in the air, too

Come on, let's get high

We'll have fun all night long

Success together, failure together

Earth bears witness to my love

I'm a yellow loser

I'm a yellow loser

I'll meet you at the cottage
