The reason is very embarrassing, why the ancient people called the wedding night "cave room"?

Many of the customs and traditions inherited from China's 5,000 years of history contain the moods of the nation's people at the time, so we prefer to inherit them. For example, we now celebrate the Spring Festival, the Dragon Boat Festival, the Mid-Autumn Festival and other festivals every year, which have their own stories that we may not be aware of now, but that doesn't stop us from spending them as usual.

During the feudal period, weddings in China were so grand, with ten miles of red makeup, that everyone laughed, and even now there are people who want to have Chinese weddings. The process of Chinese weddings was to honor the heavens and the halls, and the couples all drank their cups of wine in caves... how did caves spread, anyway? It goes back to ancient times.

The birth of the cave house was during the period when the Yellow Emperor defeated Chi You, and the marriage system at that time was the group marriage system. That is, if everyone saw someone they liked, they would stay with whoever they liked, and if the person in the middle suddenly repented and didn't want to leave, they could just leave without having to take any responsibility. However, when presented with this situation, he felt he couldn't, so he wanted to practice monogamy, or at least have it guaranteed.

Every couple that wanted to get married had to have one of these caves, and after the wedding, the bride would be brought in first, and so would the groom. Once they're both inside, they must live in the place, and their food and drink are sent to them in turn by the parents of the man and the woman until the two have established a relationship. A woman who goes into the cave single and with someone else cannot be robbed by another man or she will be punished very severely. When we came up with the idea, everyone was very supportive, so that's how it will be done in the future, and we passed it down as soon as we were in the cave.
