At present, the development trend of bars in China is mainly bouncing, which is related to the ballroom style in the 8090s. From techno music to bounce, whether it is the first bar in China or the ordinary bar in third-tier cities, bounce will be played, which is becoming more and more commercialized. Bounce dj is rampant in the market, and the entry threshold is extremely low, and some of them are even fake. The main reason is that a dj can "perform" on stage because he looks good, which also causes the confusion of dj market and is monopolized by bouncing music. In the eyes of foreign friends, it is good for our country to listen to this kind of inferior music.
