In a faraway kingdom, there was a river. It was the home to many golden swans (天鹅). The swans spent most of their time in the river. Every six months, the swans would leave a golden feather (羽毛) as a paying for using the river. The soldiers of the kingdom would collect the feathers and gave them to the king.
One day, a homeless bird saw the river. "The water in this river seems so cool and nice. I will make my home here," thought the bird.
The minute the bird landed near the river, the golden swans noticed her. They came shouting, "This river belongs to us! We pay a golden feather to the king to use this river. You can not live here."
"I am homeless, brothers. I will also pay. Please give me a place to live in," the bird pleaded (乞求). "How can you pay for it? You do not have golden feathers," said the swans, laughing. They added, "Stop dreaming and leave at once." The poor bird pleaded many times. But the arrogant (傲慢的) swans still drove the bird away.
"I will teach them a lesson!" decided the bird, feeling angry.
She went to the king and said, "Oh, my king! The swans in your river are rude and unkind. I pleaded for a home but they said that they had paid to live in the river with golden feathers."
The king was angry with the arrogant swans for having driven the homeless bird away. He ordered his soldiers to bring the swans to his palace. In no time, all the golden swans were brought to the king's palace.
"Do you think our kingdom depends on your golden feathers? You can not decide who lives by the river. Leave the river at once or I will kill you!" shouted the king.
On hearing the king's words, the swans flew away sadly. The bird built her home near the river and lived there happily. She gave homes to all other birds who came to the river.
