With the resumption of work and production of catering enterprises, "dining" has become a high-frequency word for a time. The dining room suddenly became hot, which is unfamiliar to the native people in the Central Plains. On the contrary, the word "canteen" is still fresh in the memory of most older people. In the past planned economy era, state-owned canteens and collective canteens were synonymous with the catering industry. After the reform and opening up, they were gradually replaced by various hotels. With the collision and blending of Chinese and western catering cultures, there are more and more names of foreign flavor spots, which people have long been accustomed to. "Food and beverage" was originally a kind of traditional culture in China, but after a long time, it was useless and slowly lost. As for why this word has not been used for a long time, it may be an aversion to canteens that used to be everywhere. "Dining room" and "canteen" are the same word, but their meanings are quite different. One is the form of eating, and the other is the place to eat. Therefore, "food in the hall" means that it can only be eaten in the store, generally excluding packaging and take-away.
