英文說明:This is a bwabway set which consists of two halves of bamboo root, 9 centimeters long and 5 centimeters in width. Concave shaped roots from older bamboo are selected. After the stem and smaller roots are removed, the root is split in half to become bwabway, which are used to ask the gods questions. They are tossed onto the ground and if both lay flat, then the answer to the question is not good. If one faces up and one faces down, the answer is ambiguous. If they both face up, the answer is auspicious. These bwabway are worn from many years of use.
