What's the difference between men and women?

There is no difference in meaning, they all mean to distinguish sex, and the main difference is that they are used to describe different biological sexes.

Generally speaking, if the sex of animals is represented by male and female, such as cock, hen, male dog and female dog, then it is not only domestic animals, but also wild animals such as male elephant, female elephant, male tiger and female tiger. However, when expressing the sex of plants, they are mostly male and female, such as male flowers, female flowers, stamens and pistils. Use men and women when expressing human gender.

The female symbol is ♀. It is round with a downward cross. This represents the mirror in the hands of Venus, the goddess of love and beauty in Roman mythology. It is also said that eggs will not move voluntarily, so they are marked with a cross.

The male symbol is ♂. It is circular, and the arrow points to the north or northeast. This represents the shield and spear in the myth of Mars in Roman mythology. It is also said that because sperm can move, it is marked with arrows.
