1, the main content: The poet summed up two kinds of people, two kinds of life choices and two kinds of life destinations with highly concentrated and summarized poems, eulogized Mr. Lu Xun's life as an ox, and expressed sincere praise to those who lived for the people. Contrast runs through, presenting two completely different lifestyles and their historical results in the real world.
2. Central idea: By comparing the reactionary forces with Mr. Lu Xun, this poem criticizes the rulers riding on the people's heads, mercilessly attacks the reality and praises Mr. Lu Xun's valuable spirit of selfless dedication to the people.
