What is this hairstyle called in Japan? How do you tie it? Can your hair be so honestly twisted?

This hairstyle was born out of the "Yue Dai Tou" of Japanese samurai. Generally, the head of the Yue Dynasty shaved off the hair about the width of the forehead from the forehead to the top of the head (once said, pulled out), but kept the hair from the center of the top of the head to the back of the head. The hair on both sides of the temples was not shaved, and the braids were tied behind the head.

Braids can hang down or be tied at the root of braids, with the braids facing up, as shown in the main picture.
