What do you mean if something happens?

Any unexpected disaster or accident is also a euphemism for human death.

Expansion: the historical origin of three long and two short;

1 originated from the ancient divination culture in China.

In ancient times, people used yarrow (a perennial herb) for divination, and predicted good or bad luck by calculating the "odd" and "even" numbers of yarrow. In this process, people think that "three long and two short" is a combination of numbers symbolizing ominous signs. Therefore, "three long and two short" gradually evolved into an idiom to describe death or other unfortunate events.

2. Ancient customs

After death, we should put some funerary objects in the coffin to help the deceased live better in another world. These funerary objects usually include some weapons, tools, food, medicines and so on. Among them, three things are the most important: nails, daggers and chamber pot. These three things were considered very important at that time, so they were called "three long and two short".

Why are these three things called "three long and two short"?

1, because of the way and position they were placed in the coffin. When people open the coffin, the first thing they see is the nail, which is at the top of the coffin near the head; Then there is the dagger, which is placed at the bottom of the coffin near the foot; Finally, chamber pot put it on the side of the coffin near the body. Therefore, people call these three things "three long and two short" figuratively, taking their meaning of "long" and "short".

With the passage of time, the idiom "three long and two short" has gradually been widely used. Its use is gradually expanding, and it is no longer limited to divination culture. For example, in daily life, we often use "three long and two short" to describe unexpected or unpredictable changes, such as "he is worried about three long and two short in the use of household appliances".

In addition, "three long and two short" is also used to describe people's poor physical condition. For example, "he has been in poor health and is worried that something will happen." In this usage, "three long and two short" usually refers to the situation of dying or serious physical problems.

With the passage of time, the word "three long and two short" gradually evolved into a synonym to describe the coffin, and gradually expanded to describe anything that may bring accidents or misfortune. Therefore, we often use "three long and two short" to describe some unlucky things or situations, so as to express our taboo and worry about these things or situations.
