The real essence of learning is not what knowledge you remember, but that it triggers your thinking.
You're right. There is a saying in Yi Zhongtian that there are two kinds of reading: making a living and seeking the heart. The former is just looking for a job for the college entrance examination. The latter is the reflection and comfort of the soul. Lu Xun also said that knowledge is not power, but wisdom is. Wisdom comes from thinking. We study for a better life. What can make life better is wisdom and thinking. You're right. But exam-oriented education can only make us remember. Think on your own.
