The morning glow in Peking Opera is in a falling tone. The most obvious difference between Xipi and Erhuang is the rhythm. Xipi mainly expresses bright and bright colors, while Erhuang mainly expresses deep sadness. Xipi's eyes rise and fall, that is, he beats the drum to start singing and plays the board to close the sound, while Erhuang's rise and fall. There are two theories about the origin of Erhuangqiang. One theory is that it originated from the Yihuang tune in Jiangxi; the other theory is that it originated from the Hui tune. Regardless of whether it originates from Yihuang tune or Hui tune, it is still a southern opera type, so its southern music characteristics are more prominent.
