Any art, and the appreciation of it,  are nurtured by  a specific history and a certain culture.

The Red Detachment of Women was produced in 60s, when art was a tool to serve revolutionary themes,  so it had to bear some moral imperative and political mission at that time, even it borrowed Western ballet art form.

However,  The Red  successfully integrated the ballet, a precious  classical art form, into Chinese traditional art and Chinese revolutionary war themes. 

For example, on the one hand, the folk song "Wanquan water", the well known "The Internationale" and even a Hainan Li ethnic music, had catered to Chinese people's aesthetic habits of contemporary.    On  the other hand,  the beautiful  melodies of the violin solo,  for Qinghai to pour out her sorrow,  inherited ballet's traditional aristocratic style and the grieving beauty.

All  together, they have greatly enhanced the appeal of the music of  The Red, if we put the ideology aside.
