    I'm Li Hua , a student from FenDou Middle School, that has a history of 75 years. Lie in the west of ShanBa, it has seen great changes of this old town. I am proud to tell you that I studied hard since I came here. So far, under the help of my teachers and classmates I have learned lots of knowledges. Although I still have some trouble with maths at present, I won't lose my heart. I consider it not very difficulty to learn it well as long as I devote myself to learn it. I strong believe that I can be admitted by a key university.
