The elements of human life, on the one hand, are the satisfaction of material life, such as food, clothing, shelter and transportation. On the other hand, comfort in spiritual life, such as thoughts, feelings and so on. For a long time, people generally only pay attention to material life and neglect spiritual life. Of course, in the past, we have also been restricted by the social environment. However, under the present conditions, we must attach great importance to spiritual life, correct all kinds of bad ideas in the past, make up for the emptiness of our spirit and promote the healthy development of human civilization.
