"Rise and Fall in the Fragrance of Rice Flowers", the protagonist Zhou Gufeng: In the late Southern Song Dynasty, Zhou Gufeng, a farmer from the south of the Yangtze River, moved to Lingnan to escape the war. He improved waterwheels, cultivated rice seeds, turned wasteland into granaries, and attracted refugees to join him. Later, when he met the anti-Yuan rebels, he helped the army with food and offered strategies to strengthen the walls and clear the wilderness. Although he did not go to the battlefield in person, he used farming to support the anti-Yuan foundation.
