Once there was an emperor. He had a beautiful garden. In the garden, there was a little nightingale(夜莺) singing very beautifully.
One day, the emperor heard about this little bird's beautiful voice. He asked his guards to bring her to him. When the emperor heard the nightingale's voice, he said, "Put her in a golden cage, so she can stay and sing for me whenever I want to hear her."
The little bird was so unhappy about being kept in the cage that she stopped singing one day. The emperor was very angry. He ordered the scientists in his palace to make a robot bird for him. The bird could sing very beautifully too. The emperor was pleased.
Soon the robot bird became old. It no longer sang beautiful songs. Just at that time, the emperor was ill and he became very weak. One morning, while lying in bed, the emperor wanted it to sing once again. But the robot bird could not sing any more. Suddenly, the nightingale landed on the window. She began to sing her most beautiful song. The emperor was very happy! He became better and better each day.
After the emperor was well, he changed a lot and became kind to his people. From then on, all his people cherished(爱戴) him for his love and kindness.
