When was the song about peonies and goat herders

2016. Peony Flower and Goat Herder is a Shanxi folk song released on February 25, 2016 by singers Liu Jiandong and Guo Xiaomei. A cloudy haze floats over the Helan Mountains, splendid and picturesque. It fell on the bank of the Yellow River and took root, growing into a watery peony flower. A divine deer ran down from Liupan Mountain, brave and robust, kind and open-minded, and did not want to go back to the desert, turning into a naive sheep herder.
