Only Chongwenmen had bells announcing the closure of the gates at the end of the day. The other gates used a flat instrument that produced a "tang" sound. Thus arose the saying that of "nine gates, eight tangs, one old bell". This story is a possible etymological origin of "zhongdian" to refer to the hour in the Beijing dialect. In the past there were many distilleries in the southern Daxing District. Carts would carry newly brewed spirits through Chongwenmen. This is the origin of the saying, "Chongwenmen has carts carrying spirits entering; Xuanwumen has carts carrying prisoners leaving".
