Mass is adapted from Kamana Brana (a poem by Bran). It is said that "the military song of the first armored division of the German Armed SS was also adapted here during World War II", which led to the appearance of similar tunes. Zhang Guan Dai Li thought that Mass was a Nazi military song. This is said to be unprovable, but this explanation is undoubtedly reasonable from the logic of the context. In a word, the fact is certain: it may be the same song, but it must be different. Or they just learned some elements from mana Brana. It is said that the real battle song of the First Armored Division of the German Waffen SS is called Panzerlied, which was written by Oberleutnant Kurt Wiehle of Germany in June 1933.
