The first section of this poem points out that there are two diametrically opposed people in the world today: one lives like death, and the other lives like death. People who live like death naturally refer to Lu Xun who was commemorated at that time, which is a tribute to Lu Xun's immortality. But as a typical image, it not only refers to Lu Xun, but also implies many people with the same quality as Lu Xun. As for "life is worse than death" as a negative person, it certainly refers to the bad guys.
The second, third and fourth sections compare the people who live like death with those who die like life from three aspects: image, thought and sentiment. From the image point of view, people who "ride on the people's heads" are actually insignificant, although they are cocky and call themselves "great".
He criticized the rulers and oppressors riding on the people by comparing Lu Xun's diametrically opposite "some people" and warmly praised Lu Xun's valuable spirit of selfless dedication to the people.
