"Door to door" and "Door to door" were originally the construction of ancient buildings in China. How did they evolve into marriage proverbs?

Because this kind of building appears in pairs, it is very suitable for marriage between men and women, and it has been used by later generations and gradually become a common saying today.

What modern people call "suitable" means that it is only suitable for marriage when the family background, professional status and economic conditions of both parties are very similar, otherwise it is not suitable, and it will have obstacles and influences in all aspects after marriage. Usually, "being suitable for each other" may be reasonable, but under many special conditions, this concept also separates many men and women with real feelings.

In some modern film and television dramas, there are also works describing the "main room", such as the famous drama "The West Chamber". The leading actors Zhang Sheng and Miss Cui Yingying were not suitable at that time, but with their last efforts, they finally got married, thus expressing young people's infinite pursuit and desire for true feelings and attacking the secular concept of "being suitable for each other".

In fact, "door-to-door" and "door-to-door" were used in ancient towns and houses, built at the door of the house and appeared in pairs. The "doorman" is a stone pier at the door, one on the left and one on the right. In shape, officials use circles and businessmen use squares. "Opposite the door" is an ornament above the gate, perpendicular to the lintel, and there are even numbers, some are two, some are four, and scholars mostly use squares. In ancient times, it was a symbol of status, but now there are not many such buildings, and it is difficult to see them again.

According to the architectural requirements at that time, there must be a "door-to-door". Together, the two words have been passed down to this day and become a common language to measure the marital status of men and women.
