There are many strange ethnic groups in the world besides Mosi women. The Zufinger people on the west coast of England express their joy by crying, and every festival worth celebrating, they will get together and cry to express their joy. In the virgin forest of Mexico, there is also a small tribe with only a few hundred people. This tribe is called "blind" because all tribes are blind except newborn babies, and "blind" people are blind because there is a strange parasite in the virgin forest, which will destroy the blood vessels and nerves of human eyes, thus leading to blindness.
Similarly, there are "dwarves" with an average height of only 1.4m in the virgin forests of central Africa, while Ochakikan people in Chile have blue skin, because hemoglobin only turns red when there is enough oxygen, but Ochakikan people live in high altitude areas with thin oxygen, so their skin appears blue or blue-purple.
If we look through the ancient wonderful book Shan Hai Jing, we can learn more about the strange peoples recorded by the ancients. The formation of exotic nationalities is often related to geographical environment, economy and culture, and exotic customs abound in economically backward areas. Perhaps Shan Hai Jing describes more than just legends.
