The teacher should not teach as if he were pouring knowledge into an empty vessel, but rather as if he were lighting a fire.
教师不应该像往空容器里倒知识那样教学，而应该像点燃火焰那样教学。
If knowledge can create problems, it is not through ignorance that we can solve them.
善良是幸福的关键。
The only way to discover the limits of the possible is to go beyond them into the impossible.
