We cannot teach people anything; we can only help them discover it within themselves (Galileo Galilei) (some hints for thesis writing and for the committees ). Here are some hints! Motto: 路漫漫其修远兮，吾将上下而求索. The road is long, I will go up and down to find a way. This stems from a “2000 years old” ancient poetry 离骚（Li Sao）by the most famous ancient Chinese poet 屈原 (Qu Yuan).
