What is the singing style of the four crossings of the Red River out of the strange soldiers

A combination of American and ethnic singing styles. The Four Crossings of the Chishui Out of the Strange Soldiers was created using Yunnan folk song tones, divided into two parts, Yunnan folk song tones and American voice, the music uses different singing forms and different musical moods in contrast, depicting the whole process of the Battle of Chishui. Lyrics part: the warrior two feet walk the world, the four crossing the Chishui out of the strange soldiers, the Wujiang River, the risk of heavy flying across, the soldiers are forced to Kunming in Guiyang, the enemy abandoned armor lost smoking gun ah.
