Zhang Tiezheng
I am a student in the medicine school of Shenzhen University in Guangdong,China. My knowledge of science is limited but I really love it. And I am on the road to this my favourite subject. I hope to share all that I have learnt and discovered,and the promblems which I meet in my experiments. By this way, I can make a record for myself about my life with science and get to know some people who also love science from all aroud the world.
