What is the level of a flower in the erhu repertoire?

This song is based on the Suona song of the same name (arranged by Ren Tongxiang), and the tune is rich in southwest Shandong flavor. It was once used as the theme music to describe the character of Song Wu in the TV series Song Wu. The traditional handle position and folk techniques are used in the performance, and the playing method absorbs the skills of suona and the big sliding sound and rubbing sound on the piano.
