During the summer holidays this year, I thought I should do anything meaningful instead of staying at home, so I have got a job at a KFC fast food restaurant, worked there as a cleaner．I worked seven hours a day for three weeks．
The job was hard and bored and seemed endless, which made me so tired that I nearly gave it in half way, but I stuck to it with determinations．Every day I started off for work early in the morning and got home lately in the evening．Finally I finished the job before the new term begins．
Now, I understand that labor means．I think it is really successful experience．
