He who knows others is wise, and he who knows himself is wise. Comrades who are principals should correctly understand the power in their hands and straighten out the relationship with the people. Power can be used for good or for personal gain. Our country's economy and reform system have not been completely straightened out, and some powers still lack effective supervision and restriction. Uncontrolled power can lead to corruption. In this case, it is worth pondering how principals know the power in their hands and how to use it. Power is given by the people, and we can only use it to serve the people. If the power given by the people is turned into a tool that harms the interests of the people, it is called power alienation. To prevent the alienation of power, we need to have a clear understanding of the power on our opponents. The education department has formulated many laws and regulations and promulgated many codes of conduct, but principals should also have a Code of Conduct for Principals in mind to restrain and regulate their own behavior so that they do not violate the party discipline and state laws, political discipline and professional ethics. In particular, the principals of famous domestic schools like ours should be strict with themselves, be honest and clean, lead a totally clean life, and not abuse power for personal gain.
