     During the summer holiday, I think I should do something meaningful instead touring. So I got

a job in a fast food restaurant and worked there as cleaner. I worked seven hours a day. The job

was hard and bored and seemed endless, that made me so tired that I nearly stopped it halfway.

After all, I stuck to it with determinations. Every day I started off for work early in the morning and

went to home late in the evening. Finally, I finished the job after the new school term began. Now, I

understand that labor means. I think it is really a successful experience, which is worthy remembering

for ever.
