An Introduction of myself

Hello, everyone. I am a Chinese student and my name is Lei Yu , which in Chinese denoted by "雷(Lei)雨(Yu)".
This is my first writing in STEEMIT and thank you for your reading.
I was born in Shaanxi Province which is in a deep region of China. The city I was brought up is Yan'an which used to be in charged by Chinese Communist Party(CCP) and was the capital of North China during the World War 2 and Chinese civil war.
I was bought up by my parents who pushed me to arts and started playing the piano at an early age. During my childhood, I used to play piano for 2 hours on average and it's a pleasure to remind the life as it was about 10 years ago. But finally , as the increasing pressure the class work has put on me, I stopped further developing in the tract of piano playing and put my spare time on homework fulfilling. In China, teenagers confront huge mental pressure and they have to compete for limited university quotas set by government. As a result, most teenager experience a harsh time before University Entrance Examination. Luckily, I didn't feel significantly tired.
In my university in East China University of Science and Technology(ECUST), I majored in Materials Physics and got to know some dorm-mates. They were kind to me and helped me a lot in exam preparation ,course notes sharing and homework help. I appreciate them a lot for helped me to win the exams one by one without too much difficulty.
It was in the fourth year of University, I read a book written by Simon Sigh called The Fermat's Last Theorem and stared to appreciate the huge power of mathematics and after I started my graduate program, I started to learn mathematics though it seems to be incompatible with my research work, I still get a lot of relief in reading and doing mathematics. We know that the 7 unsolved problems in Clay Mathematical Institute (CMI)'s open problem list that has 100 million
dollar attached to each. In STEEMIT, it will be my pleasure to write my thinking in mathematics though it sometimes be naive and easy, further more, I look forward to those who majored in mathematics to share their experience in University and through their description, to find a better way which suits me and helps me with some personal advices. Look forward for your feedback, Thank you.
