What is "respect for teachers, four dimensions and eight virtues, courtesy and integrity"

China's traditional rites can be summarized as "four dimensions" and "eight virtues" in terms of moral norms. "Four dimensions" refers to courtesy, justice, honesty and shame, and "eight virtues" refers to loyalty, filial piety, benevolence, love, faith, righteousness, harmony and peace. Excluding the feudal dross in "four dimensions" and "eight virtues", its essence is still worth learning. Some people summarize the traditional virtues of the Chinese nation into ten aspects: kindness and filial piety, humility and courtesy, honesty and trustworthiness, loyalty to the country, self-restraint, self-reliance, diligence and housekeeping, honesty and generosity, and perseverance. These fine traditions of the Chinese nation are inseparable from the long-term positive influence of "four dimensions" and "eight virtues" in the history of China. As long as we can treat the connotation of traditional ceremonies with the attitude of "removing the false and retaining the true, removing the rough and selecting the essence", we can learn nutrients from them, cultivate sentiment and improve self-cultivation. Today, ceremonies also have rich connotations. Being kind to others, respecting the old and caring for the young, caring for public property and obeying traffic rules are the requirements of courtesy. Helping others, protecting the environment and obeying the law are also the requirements of courtesy; It is also the requirement of courtesy to do one's job well, serve the people and safeguard the national interests.
