In the inherent impression, black hair is indeed a major feature of China people. Of course, this doesn't mean that people who don't have black hair are not from China, and it doesn't mean they can't dye their hair. It's just that on the whole, as yellow people living in this land, our hair is darker.

There is also a description of black hair in the poem. Obviously, black hair has been a symbol of China people since ancient times. Throughout the ages, we can find sentences describing black hair in countless articles and words left by sages. For example, Mr. Li Bai, a great poet, described this in his masterpiece "Into the Wine":

? Have you noticed that the lovely hair in the bright mirror in the high room, although it is silky black in the morning, has turned into snow at night. ? Blue hair here refers to black hair. In addition, some poems that we learned in our student days to persuade people to study and make progress also describe black hair, such as:

? Teenagers only know how to play, but don't know how to study hard. When they are old, they regret why they didn't know how to study hard when they were young. ? Why hair is always black The color of hair depends on the ratio between true melanin (brown/melanin) and brown melanin (red/yellow pigment). Most Asians have black hair, because true melanin accounts for the vast majority (98%). Although a few children are born with brown hair in real life, they are not black hair. Most people in China have black hair. This may be a trait that this race has evolved for a long time.

There are also people with black hair abroad, although black hair is considered to be the characteristic of China people. But foreigners also have black hair. There are descriptions of black hair in Andersen's fairy tales. We have all read the story of Snow White. The queen prayed to heaven for a child with black hair and white skin. So God really gave her such a beautiful child. There were people with black hair abroad, even centuries ago. This is why there are such records in story books, and there are not a few people with black hair. Otherwise, the king's daughter won't have the black hair in the book.

Generally speaking, although black hair does not only appear in this land, China's hair contains a lot of melanin due to the long historical choice, so that black hair is generally regarded as the characteristic of China people.
