Korean mountain?

there is this song and we sung it in choir this year

the song is Oddydong[[ however its spelled ]

Yeah it's definitely the Korean folk song Arirang. It's about this woman and the mountain. The mountain is actually Baekdu san, the tallest mt. in Korea. Its in North Korea, at the China-Korea border. Here's a translation:
Verse 1
Arirang, Arirang, Arariyo...
Arirang gogaero neomeoganda.
Nareul beorigo gasineun nimeun
Simnido motgaseo balbyeongnanda

Arirang, Arirang, Arariyo...
I am crossing over Arirang Pass.
The man/woman who abandoned me
Will not walk even ten li before his/her feet hurt.


Verse 2
Cheongcheonghaneuren byeoldo manko
Urine gaseumen kkumdo manta

Just as there are many stars in the clear sky,
There are also many dreams in our heart.



Verse 3
Jeogi jeo sani Baekdusaniraji
Dongji seotdaredo kkonman pinda

There, over there that mountain is Baekdu Mountain,
Where, even in the middle of winter days, flowers bloom.

Yeah, hope this helps (best answer)

You sang the song "Arirang."

Very famous in Korea...look up the word on the internet and you'll find tons of facts.

I'm pretty sure you are talking about Arirang.
It's a well recognized song and there are 3 verses.
The one below is verse 1 but on verse 3, it mentions a Baekdu Mountain. It is a mountain that sits between China and North Korea.

Arirang, Arirang, Arariyo...
Arirang gogaero neomeoganda.
Nareul beorigo gasineun nimeun
Simnido motgaseo balbyeongnanda.
