For those ambitious high school students who want to get into G5 or Russell Group, or for those college students in these schools, I can provide help in Chemistry, Physics and Mathematics when you meet difficulties. I get into the best University in China at that time when I was 13 years old and got top training in Sciences. I was a Ph.D. Candidate in University of Pennsylvania from 1993 to 1994 when I was 21 years old. I am a drug discovery chemist who is inventor of a cancer drug and initiated China's COVID-19 drug Azvudine project. I can provide career consulting, professional insight and systematic science training for those who aspire to develop a career in science.
