It was two years ago when I first came across a poster that read "Alltech Young Scientist Competition" while on my way to the reading room. I found it interesting and time was available, so I decided to look into the details. I met Dr. Ao and Miss Luo from Alltech and Dr. Ao's speech was so inspiring that I decided take part in the competition. However, it was my second year in university and I did not yet know how prepare a paper. I asked my physiology teacher for help. She is a reference professor and was my tutor. A few days later, I joined in her group.
