Did the ancients pay attention to knocking at the door? Why do you have to knock twice sometimes?
In the past, knocking at the door was necessary. Knock first, stop to let the people inside hear you, knock several times, no more than three times, and knock again. Knock, knock, knock, knock. In the past, knocking at the door was a funeral ceremony, which meant the dead. As long as it's not a funeral report, you can't knock continuously.
This is also a rule set by our ancestors. Han Feizi said, "Everything in the world has rules." State law, state law. If you want to be a square, you must make rules. There is discipline only when there are rules, and harmony and stability only when there is discipline.
Rules are a kind of etiquette.
There is such a wonderful fragment in A Dream of Red Mansions:
A Dream of Red Mansions: Granny Liu entered the mansion, and Grandmother Jia took the whole family to have dinner together. Among them, Li Wan and Wang Xifeng took empty seats to serve the elderly and the younger generation for dinner. After the old man and the children have finished eating, they will sit down to eat. Grandma Liu sighed after reading A Dream of Red Mansions: "It's really a gift for everyone." This rule is neither ignorance nor feudal society. On the contrary, it is a courtesy of China people to respect the old and love the young. The ancients said, "People who are polite respect others."
Following etiquette is a kind of heartfelt respect. Without this courtesy, it is very easy to lose dignity and awe.
After a long time, this family will be in chaos. During the Three Kingdoms period, Ma Chao and Liu Bei fought in the Three Kingdoms together. Liu Bei made him a general and made Hou Ting his capital. Ma Chao is a little conceited. When he talks to Liu Bei of the Three Kingdoms, he always calls him by his first name. Zhang Guan and his wife were very angry, so they decided to educate him. The next day, Liu Bei of the Three Kingdoms met Ma Chao, and Zhang Guan stood beside Liu Bei of the Three Kingdoms with weapons and equipment. Ma Chao just tried to sit down. After sitting down, he realized that Zhang Guan was standing by, and he understood at once. From then on, it is never impolite to see Liu Bei in the Three Kingdoms. Zhuge Liang of the Three Kingdoms said: "Don't be arrogant, arrogance is disrespectful, rudeness is people leaving, and people leaving are rebellious."
Rudeness is the main manifestation of arrogance. In an elite team, once someone breaks the rules and does not use management methods, their hearts will slowly spread out. Gifts are the cheapest items in the world and the most expensive items in the world. When a person understands courtesy, he can understand modesty in his heart; A family that understands etiquette can prosper; If a country is clear and polite, it can prosper.
