In 1933, the Red Army came to Yilong. 18-year-old Zhang Side and his partners bravely entered Jinchengzhai, found out the enemy's situation and helped the Red Army attack the city, and then joined the revolution.On the training ground, he gritted his teeth and transformed; on the battlefield, he took advantage of the salt field, bravely robbed enemy ships, and cleverly captured machine guns, and made many extraordinary achievements.When he fought against the six-way siege, he witnessed his comrades sacrificed to protect the people; during the Long March, he tasted hundreds of herbs and saved his comrades, putting the safety of others first.During the War of Resistance Against Japan, Zhang Side became Chairman Mao’s guard and always cared about the needs of the people.

In 1944, when the cave collapsed while burning charcoal, he pushed his hope of life to his comrades without hesitation, but he was swallowed by the loess.From a poor teenager to a revolutionary fighter, he used his life to serve the people. As Chairman Mao said at the memorial service, his death was heavier than Mount Tai, and his spirit turned into an eternal monument.
