As the saying goes, "don't be greedy for three colors, don't like one more dish." In fact, the surface meaning is easy to understand, that is, at midnight, people should sleep and not lust after women; It's late at night, so you can't overeat any more, or it's bad for your health.
The first watch and the third watch are ancient time units. The ancients divided a night into five time periods, called the fifth watch for short. The difference between each shift is two hours. One shift is 19:00-2 1:00. The second one is from twenty-one to twenty-three o'clock, and the third one is from twenty-three to one in the morning. In the evening, there are also gongs and drums patrolling the night, and the fifth watch will knock gongs five times.
By midnight, it's already deep, so it's time to go to bed. "Not greedy for three colors" is a little different from the modern lifestyle. In ancient times, because there was no entertainment, people would have a long rest time at night, but with the development of science and technology, the nightlife of modern people is very rich. After dinner, some people watch TV, some surf the Internet, and some people chat on their mobile phones, so they sleep very late at night. Most people go to bed after eleven o'clock, but people's bodies have some time to rest. Generally, after 1 1 in the evening, their bodies need to rest. This is what the ancients called a handsome guy in the third night, so the sentence "not greedy for the third night" is very reasonable.
Since ancient times, people have paid attention to "eat well early, eat well at noon and eat less at night". At night, people's stomachs are already dormant. If they eat food again, it will be difficult to digest, and indigestion for a long time will seriously affect people's health, especially the elderly. So what the ancients said is very reasonable.
Therefore, as young people, we still have to listen to "the old man's words" in some things.
