""No, I'm serious and all of you must do it with me. "Everyone was 4 at that time. They really didn't want to do it, but they had to do because the oldest man in the family was 5 important person at that time.

    The next day everyone in Yu Gong's family started to dig the mountains. They put the stones and the earth 6 the sea. One day a man saw Yu Gong and his children 7 the mountains. He told Yu Gong he would never do it. But Yu Gong said though he was 8 and would die, his family could continue to move the mountains. Then they kept on digging day after day and year after year.
