1. The teacher’s job is to stimulate children’s infinite curiosity about life.
2. Appreciate the advantages of others, be kind to the shortcomings of others, respect the privacy of others, and be happy in your own life.
3. Teachers should integrate into the mutual understanding between teachers and students.
4. The active role of educators is reflected in the use of spiritual and material educational means to exert a systematic and long-term influence on the educated to achieve their intended educational goals. The initiative of educated people is the beneficial influence exerted on them by those who work hard and are good at accepting education. Whether the education process can achieve the best results depends on whether the two active roles of the educator and the educated can be fully brought into play and whether the two active roles are well combined. ——Yu Guangyuan: "The "Three-Body Problem" in Educational Cognition Phenomenon"
5. Mortals have memory and understanding. Since fifteen years ago, when material desires have not been tainted and knowledge has not been developed, there will be more memory and less understanding. From the fifteenth year onwards, as knowledge is developed and material desires are gradually acquired, there will be more understanding and less memory. Therefore, if you have something to read, you should familiarize yourself with it before you are fifteen years old. ——Zhang Boxing of the Qing Dynasty: "Yang Zheng Lei Bian"
