That’s because I have always known about the flaw (缺陷) of my pot. I planted flower seeds on one side of the path. Every day when I walk back from the stream, the broken pot waters them.

Soon, beautiful swans (天鹅) came to the clear spring, and the village became a popular attraction for visitors.Years passed. One evening the town leaders held a meeting. As they looked at the salary list, one of them said, “Why do we keep this old man on year after year? I don’t think we need him or his work.” Later, the old man was asked to leave.For several weeks, nothing changed. By early autumn, the leaves began to fall off the trees, and the spring was covered with leaves. A few days later, the water was much darker. Only a few months after the old man left, all the swans left, as did the tourists. Disease reached deeply into the village.Quickly, the leaders held a special meeting. Realizing their mistake, they rehired the old man. Then within a few weeks, the spring began to clear up. Soon new life returned to the village.So, my friends, do you see?

In 1975, the houses of his families and his neighbors were all burned to the ground in the fire. Chen was then already married and badly needed a house to live in. But he had no money to build a house, so he had to live in his relatives’ houses as long as 5 years.In 1980, he happened to discover this cave, immediately he and his family members decided to live in there. Chen thought the cave could be a temporary(临时的)living place, but it never occurred to him that it could be his home in the next 28 years. Chen recalled that the first couple of days were the most difficult period, “I put up some wooden boards for a gate, but they were all blown away by wind that same night.”Chen has two sons and a daughter, and they all left the cave after they got married.
