However, when it is written as Kanok, it means gold. The pattern basically shows the repetition of right triangles. The triangles may be the same size or different sizes. Often the pointy part of the triangle goes right with each other in the same direction. In the Sanskrit language Kra-nok means thorns.
There are many types of Lai Kranok. The prototype of Lai Kranok is from the character of flame.
