Hugo said: "where the feet can't reach, the eyes can reach;" Where the eyes cannot reach, the spirit can fly. "The height of spirit is far from material." One scoop of food, one scoop of drink, living in a mean alley, not changing the pleasure ","A gentleman is worried about the Tao but not poor ",and Yan Hui's peaceful music shows the peace and tranquility of the soul. There are 3,000 disciples of Confucius, but Yan Hui is my favorite. The reason for this is that although Yan Hui was poor, he still devoted himself to Tao happily and calmly, which was praised by Confucius. This is what Confucian scholars in past dynasties called "the joy of Confucius". Yan Hui was diligent and studious, and was honored as the "Restoration Saint". We have understood that Yan Hui's achievement is not because of how rich his material life is, but because of his spiritual life. If he doesn't pay attention to spiritual cultivation and lingers in the material world, he may not have a better life than secular people. However, the great wealth of material and the great poverty of spirit form the most striking contrast of this era. Huang Guangyu, the richest man in China, was jailed for commercial bribery; Liu Xiaoqing, the movie star, was notorious for tax evasion; Shi Yuzhu, the chairman of Giant Network, endorsed false advertisements for profit, which made people feel bored and lonely.
