As one of the main agricultural products of Hong'an, Red Anzhen has formed an indissoluble bond with the history of the Red Anyang Revolution and the Chinese Revolution. The book "History of the Revolution of Hong'an" records such a story: In 1928, the Workers and Peasants Revolutionary Army led by Wu Guanghao was trapped on a hill by the White Army, and the grain was not touched for three days. Until the fourth day, the party representatives saw a red land on the mountainside and announced that they would allow each person to dig two red crickets to fill the hunger. After the soldiers had finished the red dragonfly, they rushed down the mountain. Three months later, the troops drove to Wangjiacun. An old man introduced the soldiers to his home. He did not know that these soldiers had eaten the red dragonfly in his place. He told everyone that three months ago, the Red Army broke out down the mountain. He went to the mountainside to dig and saw the cockroach in the ground was dug. When he dug the remaining cockroaches, he suddenly found a cloth bag with five silver dollars. There is also a letter that says, "Dear fellow, we are revolutionary troops, because we have to fight against the White Army and eat your red dragonfly. Now we have left five pieces of Baiyang. Please accept it and hope for understanding." During the War of Liberation, both the Liu and Deng forces went south, or the million males who were waiting to cross the Yangtze River. The poor Hong’an people used their only red dragonfly to welcome and send the PLA. There is such a revolutionary folk song in Hong'an: "Little Huang An, it is not simple, the copper gongs are ringing, 480,000, the man will fight, the woman will deliver the meal." Some people count that two-fifths of this "rice" is Hong Anzhen. Red Anzhen let the two presidents and 223 generals survive the famine of the youth, infiltrated into the blood of the Red Fourth Army, the Red 25th Army, and the Red 28th Army, and nurtured the battle on this land. Hundreds of thousands of soldiers and civilians.
