I would like to know the name of a Chinese song. 

I only have three pieces of information about it:

1) In the movie "Shaolin Soccer" the main character sings to the tune
of the song (with his own made up words) - I believe it is the part
where he sings to the girl who makes dumplings.

2) I heard the song many, many times when I took a trip to Guilin. I
remember our tour guide saying it was like the famous song from those
parts... I think two verses were supposed to be sung back and forth
between a boy and a girl who liked each other but were also making fun
of each other?

3) This is a real stretch, but each verse has two lines that end in
something like, "tai liao liao luo" (I may have that wrong because I
never asked anyone the Pinyin!)

Please give me the name of the song in as many languages as possible
(English, Chinese characters or pinyin would all be acceptable, and
hopefully all three), including any alternate titles it may have...
also if you know anything else about the song, or any CDs that have
the song on it, it would be most appreciated!

Is it the song described in this discussion board?

(I haven't seen the movie, so I don't know if that's the right part or not)

No, it's just a simple folk song that the main character makes up
words to. I'm pretty sure what they're referring to isn't it.

It's a famous folk song made by Liu San Jie(Mrs Liu-the third daughter
in the family Liu). This song is a Questions and Answers song, name
Dui Ge. In the movie Liu San Jie, boys and girls used this tune to
play games. They need to ask and answer in this tune.

Thanks! Where could I possibly find a CD with this song on it? (or an mp3?)

That movie isn't available for purchase online :(

I have found an mp3 of a Chinese song called "Dui Ge," but I do not
know whether this is the same song:

to pinkfreud: What you got is the official song of the Chinese Youth
Pioneers. It's a league for children at elemental school age. The
meaning of the song is " We are the glorious communistic successors."
It's not what boney is looking for.

I don't like this version.

A freak modern R&B version. It's awful.
