Professor Liao Shantao is a typical Chinese inttellectual.He worked extremely hard to pursue the truth in mathematics for his whole life.He was still drawing mathematical figures on a piece of paper at the night of June 5 1997,a few hours before he left the world at age 77.This proceedings is the best way for us to pay respect to this spirit which will be with us forever.
