What is Cao Zhi's poem about life and death?

From Cao Zhi's "Death from National Disaster" to Wen Tianxiang's "Who has not died since ancient times, take history as a mirror"; From Tan Sitong's "I laugh at heaven with a horizontal knife" to Xia's "beheading doesn't matter, as long as Taoism is true", we have seen the simplest and most incisive interpretation of "life and death" made by benevolent people.
