What is an excerpt from the quintessence of Chinese studies?

Excerpts from "The Essence of Chinese Studies" are as follows:

1. If you commit a crime in heaven, you can still violate it. You can't live if you commit iniquity yourself. -"Shangshu"

It means that if a person causes disaster, there is no way to escape.

2. Learning is not enough, but teaching is difficult. -"Book of Rites, Learning"

So I didn't know I was wicked until I studied deeply, and I didn't know I had no knowledge until I taught and educated people.

3, Dade is not idle, and Xiaode can enter and exit. -"The Analects of Confucius, Zhang Zi"

Don't cross the line in moral practice, but it is ok to make some differences in small details.

4, the years are cold, only to know that pines and cypresses are dying. -"The Analects of Confucius Zi Han"

The coldest season of the year, let us know that pine and cypress will not wither.

5. The benevolent regards it as benevolence, and the knower regards it as knowledge. -Zhouyi

A benevolent person regards this as benevolence, and a wise person regards it as wisdom.
