I'm sorry, but I'm not sure if you're going to be able to find a song that has the lyrics to this one, but I've heard this one, and I think it's a TV commercial.

"Little Poplar", lyrics by Liang Shangquan, music by Shixin.

Edit Song Lyrics

A small poplar, grown next to the post Roots deep, stem strong, watching over the northern border Breeze blowing, blowing the green leaves rustling Luo Fei The sun shines on the green leaves shining silver Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here Come here I'm going to plant it as if my hometown was next to me.
