On May 29th, the Political Bureau of the Central Committee of the Communist Party of China held its fifth collective learning on building an educational powerhouse. This insightful and concise statement enriches the ideological connotation of the important discourse of the "Four Haves" good teacher, and provides a clear direction and path for how to cultivate a "Four Haves" good teacher. The four words' firm ',' nurturing ',' nurturing ', and' diligent cultivation 'are concise and profound, and are worth savoring in detail. Firm ideals and beliefs. 'Firmness' means that ideals and beliefs are rooted in oneself, and the saying goes that the Tao is not far from others and does not wait for external demands.
