This is a song by some guy who wrote it. It is not the original version. Is a joke version. 2 . I heard some guys sang it like this.

"Đoàn quân Viet Nam đi,
sao mà ốm thế
sách cây giù đi ngan chùa ấn quang
chèo lên núi kiến cán xưng hòng giái
xức giầu thơm nam phút xưng tròn gio"

Shut the hell up shanghaislut.

Erh... may be not.

Imagine if one of us Vietnamese posted something similar to that in the Chinese section.
You either trying to start a flame war or asking to be flamed.
