In ancient times, giving a knife also meant wishing you good health. Only healthy people can dance with knives and sticks. The ancient emperors also gave knives to military commanders who made great contributions, and Japanese sabers handed over by the Eighth Route Army during the Anti-Japanese War were also given to brothers as gifts.
There is another meaning in current culture: sending money to. That is, the homonym of "sending a kitchen knife" means wishing you a fortune. It is similar to sending a coffin to an official, which means promoting to a higher position and making a fortune. It has many meanings, all of which mean blessing and good luck.
Different countries have different customs of delivering knives.
1. In Japan: you can't send knives to the Japanese. It means let him kill himself.
2. In France: swords, knives, forks, tableware and other items are not allowed. It means that the two sides will break off relations.
3. Uyghur: Parents should carefully choose the dowry for their daughters. Needle and thread can be sent, but knives and scissors can't be sent, so as not to misunderstand it as "make a clean break."
