Huahuachangzi originally refers to a woman's fallopian tube. Why has it become a derogatory term now?

This has evolved step by step. At first, it did refer to women's fallopian tubes, but later, people extended this meaning with this twisted intestine. Finally, I found that it can also describe a person's mind of eighteen bends in a mountain road, so it gradually became a derogatory term.

Huahuachangzi, slang. The original meaning refers to the ovary and fallopian tube, which is a popular saying. Because it looks like the intestine in the abdominal cavity and is close to the intestine, the knowledge of ancient anatomy in China is not popular, and this term is often used by butchers or eunuchs. The source is Wang Shuo's "Don't treat me like a person": "I feel dizzy at the sight of water, and I spit out my intestines after sitting on a boat for two hours without wind or waves."

Now huahuachangzi is a metaphor for treacherous plans or people with treacherous plans. The origin of the idiom: Chapter 4, the second half of Feng Deying's "Mountain Ju Ju": "This scholar returned with more flowers and intestines than other areas." Emotional color is derogatory.

The development of every idiom is formed through long-term extension. At first, people said this idiom only because of its superficial meaning, and there was no other obscure meaning. This kind of flower intestines is only available to women, but in real life, people think its shape conforms to the ideas of some men.

People often say that men are playboys, and the first two words of this idiom happen to be flowers, which is also very consistent. The shape of the intestines is just in line with men's psychology, and men have tried their best to achieve their goals. So up to now, most of what we know is extended meaning. It can only be said that human wisdom is great, and the origin and extension of many idioms are also in line with the status quo.
