Introduction to the entrance gate: A couplet is engraved on both sides of the gate of the cemetery, which is a poem by Comrade Mao Zedong: "For the sake of sacrifice, I dare to ask the sun and the moon to change the sky." On both sides of the couplet is a quotation from Mao Zedong. On one side it says "Sacrifice for the country and you will live forever"; on the other side it says "If you die for the people, you will be honored even if you die."
