Nine Songs of the Moving Heavens (Chinese: 天行九歌; pinyin: tiān xíng jiǔ gē), is a Chinese animated CG TV series that was released on March 10, 2016, and produced by Robin Shen and directed by Chen Qianyuan.

In an interview with Robin Shen, it was stated that although the two animated series have intersections of characters and timelines, Nine Songs of the Moving Heavens is an independent story with the focus on the creation of the Quicksand group by the Ninth Prince of Han, Han Fei.
