The word of Uro is originated in U (a crow) and Ro (a white egret).

These two birds are related to a black stone and a white stone of Go game. Two legendary wizards are playing the game of Go and a wood cutter carrying an ax on his back is interested in watching the game from the outside.

A long time has been passed.

When a wood cutter came to notice it, his wooden handle of an ax had been spoiled.

A legendary Wizard's life is quite long and it differs from human beings. 

This story suggests us how to spend a life significantly andif we neglect our works a life will be collapsed.

When hooking with things long, we forget ourselves.

Without worrying about the trifles and do always have generous feeling in our life.
