Personally, I think it is very necessary to maintain good manners and etiquette in daily study, life and work. Paying attention to etiquette and observing etiquette norms can effectively show a person's education, demeanor and charm, better reflect a person's cognitive level and respect for others and society, and make personal knowledge, cultivation and value recognized and respected by society. Appropriate etiquette can not only give the public the trust and desire of affability, respect and cooperation, but also make the process of cooperation with the public full of harmony and success.
