In these two days, I took part in an activity in Xinhua bookshop. My job was to introduce the books which were well-sold to the readers and help the readers find the books that they want to buy or read. Firstly, the employee of the bookshop told us the location of every kind of books and the way to use computer to find where the books are. Then, I received a working card. I hung it in the front of my chest. Everyone who saw my card would ask me for help. The floor I served for was only for kids. I found that many parents and students were worried about the examinations. I shared my experience which I gained from my junior high and primary school with them. After understanding what I said, they got a right way to choose the right books for them. Secondly, I helped the orders find the books they want and told them the method of using computer to know where the books are. Finally, I received my certificate of merit from the bookshop. They were satisfied with my job in the bookshop in these 2 days. From this, I gained lots of experience and knowledge from this job, which would influence my whole life. If it is possible, I will do it again in my summer vacation. Helping others can give me a lot of pleasure.
