Mongolian women often use a branched wooden stick as their headwear. The branched end is wrapped with cotton into a knot, and then is sewn up with a piece of cloth. When a girl gets married, she will undo her pigtail and separate her hair in halves from the middle, with each half plaited into many small tails. Put the tails on one side over this wooden knot evenly, use a leather lace to fasten them under the knot, and then the hair and wooden stick are fixed together. Then, she will insert it firmly into a cone-shaped hair cover, with a ribbon hanging below. At the knotted part, a semicircular ornament should be covered, with a button fixing it on the knot from behind (inside). The whole combination is called Lianchui.
