The poem "Teacher, cultivate one's morality and find mountains and rivers" comes from a famous saying in ancient China. Specifically, this poem is from Zhuangzi Heaven. The original text is as follows:

"Teacher, cultivate one's morality with good deeds and collect mountains and rivers. Those who are rich in mountains and rivers are talented in heaven and earth; And the teacher, the heart of heaven and earth is also. Where the heart goes, where the talent goes; Where talents gather, people's hearts return. "

This poem expresses the virtue and influence of teachers, and thinks that teachers can harvest mountains and rivers with their own moral cultivation. The "mountains and rivers" here represent everything in the world and emphasize the importance of teachers' moral quality to the world. At the same time, this poem also emphasizes the connection between teachers and heaven and earth, thinking that teachers are the heart of heaven and earth, while mountains and rivers are the talents of heaven and earth. When the moral quality of teachers is carried forward, talents from all over the world will gather here.
