I have also watched it in San Francisco International Film Festival ... Unfortunately they have REMOVED the song (but the scene exists) ... This is puzzling ... I thought they should keep the song which is rather meaningful ... (even if they refuse to subtitle the song)

thanks and acknowledgement to ent.sina.com.cn
the following is dedicated to those who like one of the Mongolian folk songs (I think) in the movie ...

(you can ignore the Chinese fonts ...)

The lyrics (loosely translated by me) are:

Song Title: The Night of Ulan Bator

The wind that sweeps through the wilderness 
Please do not leave so soon ...
I use my silence to tell you ...
I am drunk ...

The clouds that sail to a distance ... 
Please do not leave so soon ...
I use my run to tell you
I won't turn back ...

[Chorus]
The night of Ulan Bator ...
All is so quiet ... all is so quiet ...
Even the wind does not know of me ... it does not know

The night of Ulan Bator ...
All is so quiet ... all is so quiet ...
Even the clouds do not know of me ... they do not know
[End of Chorus]

To those who have wandered to a foreign land
Where are you?
My stomach begins to ache
Do you know?

The birds that fly through the firy flames
Please do not leave
Do you know that tonight, it has become crazy
Not just for you ...

(repeat Chorus 2x)
