    Then I was a high school student from low-income family.So I had to support my family.My first job is to clean the table in a small restaurant.I still remember going there early and feeling anxiously about the new world.I worked hard but I was afraid of losing the job.At night，I was sometimes very tired that I didn't want to do our homework.I came to understand that it was difficulty to earn money，and that knowledge could change into my life.And what I learned from the job was much more important than the knowledge learning from school.
