The Mongolians in northern China have a vast distribution and a long history. Chor music is the cultural heritage of Mongolian in the north. After the rise of "Intangible Cultural Heritage upsurge" in the 21st century, scholars and folk artists rose to protect it and there were successively studies on Chor music theory, Chor music form and Chor historical evolution. However, scholars only focus on the research on the origin, classification, evolution and protection of Chor music, while the research on the relationship between Chor music and modern culture, summarizing that Chor music can be widely spread and recognized in modern society is lacking. This study mainly adopts qualitative methods in empirical research with literature research, field investigation and interview etc. to discusses the modern forms of Chor music, analyze the adaptation techniques in modern Chor works and identifies the musical elements recognized by the public. Therefore, we draw the conclusion of four-dimensional protection methods which includes preservation, innovation, crossover and communication.
