爱是世界上最强大的力量。
You cannot get smart people to work extremely hard just for money.
唯一的好是知识，唯一的恶是无知。
The love of a teacher is like drops of dew, which can revive even a withered soul; the love of a teacher is like a warm spring breeze, which can melt even frozen emotions.
When a thing is funny, search it for a hidden truth.
一个人直到能够超越个人利益的狭隘局限，关注整个人类的利益，他才真正开始生活。
