Eating behind closed doors is the pulp owner not at home or is it said that he was denied entry

Generally speaking, a closed door is when the host who needs to visit does not allow guests to enter.

Source: Tang Feng Zhen "Yunxian Miscellaneous Notes: Misty Fragrance Cave": "Shi Feng, Xuancheng prostitute.

Hospitality is equal to ......The following do not meet each other, and they will be treated behind closed doors. "It is said that he only treats guests with soup and does not meet with each other. The latter refers to refusing to enter the door and not meeting each other.

Qing Ershisheng "Shizhou Spring Language, Pinyan": "Those who have not seen it for three years, and I plan to revisit it, I am afraid that it will be a closed-door story." ”

In layman's terms, it is:

Legend has it that in the Tang Dynasty in China, Xuancheng woman Shi Feng looked like a flower and jade, proficient in piano, chess, calligraphy, and painting, so many young men came to visit her one after another, hoping to become friends with her, but many people could not do so because it was difficult to see her. Why is it so hard to see her? Because there is an unwritten rule when she meets guests:

She first asks the guest to present a poem, and only after she likes the poem is she willing to meet the guest, and then it is possible to talk about making friends.

If the guests did not know how to compose poems, or if the poems offered were not favored by her, she asked the family to treat them with a bowl of soup at the door, and politely refused to entertain them.

After a long time, the visiting guests saw the soup, and they understood it, so they took the initiative to leave.

Treating guests with soup means refusing to meet, so people call this soup Shi Feng's "closed-door soup".

After this story was handed down, people used "closed doors" as a synonym for rejection.
