KuaFu Chased the Sun
It is said that in antiquity a god named KuaFu determined to have a race with the Sun and catch up with Him. So he rushed in the direction of the Sun. Finally, he almost ran neck and neck with the Sun, when he was too thirsty and hot to continue. Where could he find some water? Just then the Yellow River and Wei River came into sight, roaring on. He swooped upon them earnestly and drank the whole river. But he still felt thirsty and hot, thereupon, he marched northward for the lakes in the north of China. Unfortunately, he fell down and died halfway because of thirst. With his fall, down dropped his cane. Then the cane became a stretch of peach, green and lush.
And so comes the idiom, KuaFu chased the Sun, which becomes the trope of man's determination and volition against nature.
