2. Midnight snack now generally refers to food at night. Midnight snack can be food at night or time (very late).
Midnight snack refers to the meal eaten in the evening, that is, the meal after supper, and the time refers to the rest time (usually after 12 and before 4 am, because 4 am is the morning tea time in Guangdong). In the city, there is almost no difference between the choice of supper and dinner, but teenagers often eat supper all their lives, which is caused by the extension of work or entertainment time.
"Liang Lumeng" in the Song Dynasty said: "On New Year's Eve, the internal affairs office presents a fruit box for supper, and all kinds of exquisite fruits are clustered (gathered) in the box: seasonal fruits, preserves, preserves, etc." "midnight snack" is also called "midnight snack", which has existed since ancient times.
The "snacks" in Ci Yuan notes: "Cantonese night market restaurant is also called snacks." This statement is not appropriate. Snacks include porridge, noodles and sugar water. Cantonese people enjoy these foods in the afternoon after meals, which is called "eating snacks", and "night market restaurants" are places to eat snacks. Strictly speaking, the earliest "midnight snack" refers to dinner, but this dinner is not a home-cooked meal but provided by a brothel.
Eating too much at midnight will make your stomach swell and oppress the surrounding organs. After meals, the intense work of the stomach, intestine, liver, gallbladder, pancreas and other organs will send messages to the brain, which will make the brain active and spread to other parts of the cerebral cortex, causing insomnia. If you eat too much unreasonable and unhealthy food at night, plus less activity, the food in your stomach can't be emptied in time, and the normal pace of life is broken, which will easily lead to insomnia.
