STORY OF THE KOI FISH AND THE DRAGON
An ancient tale tells of a school of koi swimming upstream. Gaining strength by fighting against the current, the school glimmered as they swam together through the river. When they reached a waterfall at the end of the river, many of the koi turned back, letting the flow of the river carry them away.
The remaining koi refused to give up. Leaping from the depths of the river, they attempted to reach the top of the waterfall. Their efforts caught the attention of local demons, who mocked their efforts. Finally, one koi reached the top of the waterfall.
The gods recognized the koi for its perseverance and determination and turned it into a dragon, the image of power and strength.
