In 1946, Wu Wen-ji studied vocal music in Sikang Province in China. At the same time, he composed a song named Paomao Liuliude Shanshang. This means "Running Horse Mountain" in English. He also composed other local folk songs. When he was teaching at a Kuomintang military academy, he renamed the song as Kangding Love Song. He renamed it after the capital of the Sikang Province. He also changed some of the lyrics. The song then spread to the rest of China. This is due to the song being sung by a popular Soprano named Yu Yixuan.
