Bon bon chicken is a popular dish in Chinese cuisine. The name bang bang chicken is derived from the manner in which the meat is tenderized using a stick or hammer.
Someone came up with a strategy: cut the whole chicken into thin slices and sell it by slice. This strategy proved to be very effective, and "chicken slices" gained a good reputation. However, another problem occurred: a kitchen knife could not cut a whole chicken into slices evenly, and customers are often picky when making purchases.
However, it was found that beating the chicken into pieces with a giant stick would solve this problem. At the same time, juice broth infuses into the chicken and adds flavor. When preparing the dish, one holds a stick and another holds a knife; the sound made by the stick and the knife striking each other has a rhythmic, almost musical quality, hence the name bang bang chicken.
