After the southerners didn't understand that the northerners were hoarding 100kg of Chinese cabbage for the winter, and the northerners didn't understand that the last dish ordered by the southerners must be stir fried vegetables, the "dish" caused discussions between the South and the north. It is said that northerners must have a hard dish to eat in town. In fact, it is true.
Recently, micro blogger @ I am a micro blog of Feizhi attracted the attention of southerners. What? You northerners must have a hard dish for dinner?
