Kua Fu was a man of
great strength. He could not bear to see the people suffering in
darkness all day long, without the sun shining upon them. So, he decided
to race with the sun to bring it under his control. The sun agreed to
rise and set on time if Kua Fu could catch up with it. After innumerable
hardships, he did catch up with the sun, but he himself died of
exhaustion.
