The arrow fly like a vulture and pheasant, its head of arrow looks like an pillar in the fortress and temples, the golden thread used to wrap on the head of arrow is like colourful rainbow and the iron arrow head used was like the shining sun, the arrow can destroy its enemy in war and it can be kept on the shrine as sacred object.
