1. Therefore, the disciple does not have to be inferior to the teacher, and the teacher does not have to be wiser than the disciple. There is a priority in learning the Tao, and there is a specialization in the art, that's all. ——"Teacher's Theory" written by Han Yu in the Tang Dynasty.

Meaning: Therefore, students are not necessarily inferior to teachers, and teachers are not necessarily wiser than students. They hear the truth earlier and later, and each has his own expertise in knowledge and skills, that's all.

2. When three of us travel together, we must be our teacher. Choose the good ones and follow them, and change the bad ones. ——The Analects of Confucius by Pre-Qin Confucius.

Meaning: If I am traveling with several people, there must be someone among them who can be my teacher. I choose his strengths to learn from him, and when I find his shortcomings (if I have them myself), I correct my own shortcomings accordingly.

3. Green is better than blue. ——Pre-Qin Xunzi's "Encouraging Learning".

Meaning: Indigo is extracted from indigo, but the color is darker than indigo. It is a metaphor for a student surpassing a teacher, or the descendants being better than the predecessors.

4. Therefore, there is neither high nor low, neither long nor short. Where the Tao exists, the teacher exists. ——"Teacher's Theory" written by Han Yu in the Tang Dynasty.

Meaning: Regardless of high or low status, regardless of age, where the truth exists, there is a teacher.

5. Attacking my shortcomings is my master. ——Wang Yangming of the Ming Dynasty, "Zhuan Xi Lu".

Meaning: When criticizing and attacking others, we should first reflect on the fact that I do have such a problem. These criticisms and attacks are of great help to my own growth! Therefore, other people's attacks and criticisms become the best teachers.
