There are no completely calm seas, just as there is no life without hardship. Waves add grandeur and beauty to the ocean, while difficulties leave behind moving memories in life. Life is a difficult book to read, and only by reading it with care can one understand its true meaning. Life is not a game, and the hardest thing for people to achieve is a truly optimistic outlook; therefore, those who can live a truly happy life are rare. If ideals are the thesis of life, then diligence is the evidence that supports it. Life is like a complex and puzzling jigsaw puzzle that requires continuous exploration and assembly. Kindness from others should be met with appropriate responses; otherwise, it goes against basic etiquette. However, in real life, this sense of etiquette is often misunderstood. Some people, in order to save face, give excessive gifts and money during weddings or funerals, creating heavy burdens. Some, driven by loyalty among friends, intervene recklessly for others and eventually fall into illegal activities. Even worse, some use the excuse of reciprocity to engage in corruption such as power-for-money, power-for-sex, or power exchange. All of these are misunderstandings or distortions of the concept of etiquette.
