For the first time in Hong Kong's history an entertainer（艺人） has been written into middle school text books. He is considered one of the best actors in Hong Kong. Yes，he is Chow Yun-fat .

The example of his long hard struggle for success has been used in a chapter （章节）in a Hong Kong middle school textbook. Using his experience，students can learn to make the most of their time and to grab（抓住） every opportunity to succeed.

On hearing about this，Chow said happily，"I really hope that my experiences can make young people understand that one should not be afraid of difficulties and setbacks（挫折） ，for they are the only way to success."

Indeed，Chow has traveled a long and difficult path to reach his success. In 1955，he was born into a poor family in Hong Kong. When he was 17，he had to leave school. He worked in a number of jobs-as a postman，camera salesman and taxi driver. These experiences paved（为...铺路） the way for him to play all kinds of roles late in life.
