An
ancient Chinese parable is told of Yu Gong, a 90-year-old man whose
travels to and from his home were inconvenienced by two large nearby
mountains.
One day Yu Gong said to his family, "These mountains are too inconvenient. Why not get rid of them?"
His son and grandson responded, "What you say is true. We shall start moving them tomorrow."
The next day, they began moving the mountain, carrying stones into the sea.
They worked nonstop through summer and winter, rain and snow.
Observing their work, a man said, "Yu Gong, you are so old. Do you really think it is possible to move the mountains?"
