This sentence came from Sima Tan, a famous historian, writer, and ideologist of the Western Han Dynasty. The original text was: "Death is either heavier than Mount Tai or lighter than a feather." However, there are heavy things in heavy things, and light things in light things. When it is heavy, people will look up to it; when it is light, people will rush to it." The meaning of this sentence was that everyone had the fate of death. They might die noble and meaningful like Mount Tai, respected by people, or they might die humble and insignificant like a feather. However, the meaning of nobility was different from that of humbleness. At the critical moment of life, people would judge the meaning of their lives according to their value and contributions.
