About Myself

My name is Qin Zheng. I am from Xiangshan, which is a small town in Ningbo District. It is very beautiful and nowadays a lot of films and TV programmes are shot there. More and more people went there for a holiday. The people there are laborious, virtuous and warm hearted. I’m much felicitated that I was born and raised up there. It is my hometown and I will love it forever.

My family has been engaged in farming for generations. My relatives are all farmers. My ancestors and my parents have plotted all their life on thin ground. In my family, my father, my mother and I, that’s all.

Now I’m in grade three, a third year student in Jiaxing University. Since I have made a lot of friends, I find life in this university both happy and rewarding. I live happily here. I like climbing mountains. I like singing, listening classical music. I like essay, also novel, but my favorite is essay. Unfortunately, although I have read so much, my writing is still not very good.

I hope that I can be an useful person for our society. But at the moment, my knowledge is still not rich enough. In order to realize my objectives in life, I will study hard and gain more and more skills and knowledge, such as speaking English and using computer. If I have enough money after graduation from school, I will study driving. It is good to have a good job when someone can drive a car or a bus.
