1. Deep affection is a burden that I cannot bear, and words of love are just lies that come true accidentally. —— Zhang Xiaoxian

2. There is necessary love between us; but at the same time, we also realize that accidental love is needed. ——Sartre

3. Scientific inspiration can never come by waiting. If there are any accidental opportunities in the development of science, then such "accidental opportunities" can only be given to those who are well-educated, to those who are good at independent thinking, and to those who have a perseverance spirit. Not for lazy people. ——Hua Luogeng
