Since I was a child, I have always been fascinated by science, especially mathematics.  Not only do I have the interest in natural science, but also do I process special talent in the aspect. 
Before entering the university, I was selected for the Elite Class to receive advanced education in mathematics and sciences. With the exposure to many national competitions, I became additive in mathematics
 for that I really enjoy each success in chasing for the accuracy. Owing to my enthusiasm and efforts, I ranked Top 200 among about 450 thousand of examinees in College Entrance Exam in mathematics, 
of which the percentage is much smaller than 0.1%.
