My name is Chen Nan. I am 31 years old this year. I am an assistant teacher at a university and a science assistant at the School of Biology, the Provincial Academy of Sciences.I have loved biology since I was a child and liked Darwin's books the most. I am also very interested in the subjects of evolution and biology specialization.My family’s conditions are not very good, but my family still put me in laboriously to college. I chose the subject of biology because of my preference. Although I am a scientist after further studies and have obtained a doctorate degree, it is really not easy to make a lot of money in this subject, and it is not easy to succeed or become famous.I was a PhD when I was just 31 years old. This is an envy of many people, but I am just dissatisfied and have been putting myself under great pressure.My colleagues all said that I was a crazy man, a crazy man. Once I started researching and investigating, I was so focused on it.But what's the use of working so hard?Every time I publish my own research results and papers, it will be scattered. None of them can cause a sensation.
