The Long March is a bitter course, but it also has its special function. For the Long March, Mao Zedong summed it up like this: "The Long March is a manifesto, a propaganda team and a seeder. "Wherever the Red Army went, the revolutionary fire was spread, which made many people see the future and hope of the nation. More people joined the revolution and more revolutionary base areas were born. Practice has proved that the Red Army's Long March planted trust in the hearts of the people and gained the hearts of the people on the land of China.
