In the past the man has been first; in the future the system must be first.
The true aim of education is to awaken the soul.
The best way to get out of a situation is to never get into it in the first place.

黑暗无法驱走黑暗，只有光可以；仇恨无法消除仇恨，只有爱能做到。
The path to sustainability is paved with both challenges and opportunities.
