Some people die for the benefit of the country, society and people. Those people are selfish and dedicated to others, so they are more important than Mount Tai. Although they are dead, they still live in the hearts of the country and the people. Some people live frequently for their own self-interest, or are content with the status quo and have not made any contribution to the country, society and people. Ordinary life will be forgotten by history and people after death, so it is as light as a feather.
