In the past five thousand years in China, countless scholars have developed the traditional culture of China in their own way, among which Confucianism is the most famous. Up to now, we have been constantly imitating and learning the words of many Confucian masters, such as "reviewing the past and learning the new" and "learning today is better than keeping your word", which has given us a lot of positive influences. Among these famous sayings, there is a well-known saying throughout the ages, "life and death are life, and wealth is in the sky." The main idea of this sentence is that life and death are predestined, whether a person can be rich or not is decided by heaven, and nothing can be changed by himself. So many people often use this sentence to vent their emotions after being frustrated. However, the source of this sentence and the idea that the speaker wants to convey are not negative. The central idea is in the second half of the sentence. Compared with the reputation of "life and death are life, wealth is in the sky", its next sentence is "ten people don't know" To say the true meaning of this sentence, we must first say the source of this sentence. During the Spring and Autumn Period and the Warring States Period, there was a nobleman named Sima Niu who was driven to Lu because of problems in his life. When Sima Niu was in Lu, he learned about the Confucian culture in Lu. He was very interested in this, worshipped Confucius and became one of the many students under Confucius' seat at that time. Among these students is Xia Zi. Xia Zi is one of Confucius' favorite students. Confucius often praised his apprentice in front of many people, saying that he was clever. He thinks that Xia Zi can best understand his own ideological core and often goes out with him. Other students also admire Xia Zi's knowledge and achievements and often talk and laugh with him. Sima Niu Yi, a freshman in a foreign country, felt a little uncomfortable when he saw that other people had such a good relationship. He privately complained to Xia Zi that everyone else was taken care of by friends and teachers, but he was always alone. In the face of Sima Niu's complaint, Xia Zi said this classic Confucian saying: "Life is death, wealth is in the sky. A gentleman is respectful without loss, respectful to others, and brothers all over the world. Why don't gentlemen have brothers? " If this passage is separated, the first half is full of negative meanings, but the second half reverses the overall central idea. Xia Zi means that although some things are arranged by heaven, as long as you respect others and don't make any mistakes, you should pay more attention to etiquette in the process of communication. In this case, the people around you will become your brothers.
