Spicing up proper Beijing Mandarin with a dash of humor in a local dialect is nothing shocking or unheard-of. This technique, called qiekou huar, frequently draws upon miscommunications between different dialects brought about by mispronunciation or hearing the wrong word, and through mutual mockery or sarcasm, causes people to reflect upon themselves.
至於在正統的北京話裡加點方言的笑料，也不是什麼稀奇新鮮事，一般稱之為「怯口活兒」，在不同的方言間找尋因誤說、誤聽而造成的誤解，從中互相調侃，或是從諷刺裡做一番反省。
