Due to misunderstanding in China, DJ has long been regarded as a musical style, but in fact DJ is not a musical style. Many people will mistakenly call it DJ, which is what people call vulgar behavior, or the music that mistakenly calls "DJ" is actually electronic music. This technical term cannot be used to replace the existing music style. At the same time, dance music is easily called "DJ dance music" in China.
