                                                                            Too Pleased with Oneself

     In the Spring and Autumn period, there was a major minister, Yan Ying. He was very wise and always treated people

with the best manners. So he was very highly respected.

     Yan Ying had a wonderful horse and carriage(马车).When his driver sat on the carriage, driving for such a great man,

he felt quite proud about it. One day, as he was driving the carriage past his home, his wife saw him sitting at the front

of the carriage so proud that she found it uncomfortable, and was quite ashamed of(以…为耻辱) him.

     That evening, when her husband came home, she told him that she felt sick when she saw how proud he was when

he drove the carriage for Yan Ying.  She said,''Yan Ying is a major minister, and highly respected. But he sat in the

carriage without any pride. You are only a driver, but you looked as if you were an even greater man than Yan Ying. I

don't want share the same room with such a person!" He thought about it, and realized that he was wrong. He promised

her never to behave that way again.

     From then on, the driver tried to learn from Yan Ying. Yan Ying noticed this, and asked his driver what had caused

him to change. The driver told him what happened. Yan Ying was impressed by what the driver said. Later, he offered

him an official post.

     From the driver's previous(先前的) behavior comes this useful phrase"yang yang de yi". We use it to describe big

heads, people who are far too pleased with themselves.
