Qinghai minor "Looking at Mom Behind Nanshan" is a folk song, which is passed down from mouth to mouth by ordinary people, and the original song cannot be traced back.
Lyrics: Today, my heart is in a mess. Behind Nanshan, I looked at my mother. I didn't take anything in my hand. I didn't take anything in my hand. I took the key and opened the cupboard. I found 300 yuan in the box.
