According to Baidu Encyclopedia, "Please Come to the Grassland" is a song sung by Monk, with lyrics written by Liu Xinquan and music written by Shi Yan.
Lyrics of "Please Come to the Grassland": The years are warm and the memories are familiar. Who beat the horse and hurried back and forth, the wind bloomed. Grassland is like the sea of Wang Yang, and life is like the tide. Please come to the grassland and be happy for thousands of miles. Getting drunk is happiness, waking up is sweet. Seen the prairie, the land is vast and the people are tall. From then on, it was refreshing and boundless.
