So when children got their first haircut, the hair which covered kwan is left. This lock of hair is called a topknot. There are four kinds of topknots, joog , klae , pia and ko . Joog is the hair knot in the middle of the head. Klae is two locks of hair, one on the left and one on the right side of the head.
Some children have only one klae , and some have two.
Pia is a lock of hair on the top of the head like joog , but it is a pigtail instead of a knot. Ko is a lock of hair which is simply knotted at the back of the head. The way of choosing is very strange. First, the parents made four little dolls from clay. Each had a different kind of topknot.
