According to Netease Cloud Music website, "Little White Poplar" was composed by Liang Shangquan and Shi Xin, included in the album "Song of Karamay" and released on March 1990.
Some of the lyrics are as follows: a small white poplar, growing beside the post, has deep roots and lush leaves, and its children are strong, guarding the northern Xinjiang. The breeze rustled the green leaves. Hey, the sun shines on the green leaves.
