After returning to her hometown, He Yuemang found that the lotus pond had low efficiency and decided to promote lotus-fish co-culture, allowing the lotus pond to produce lotus roots and raise fish at the same time. She teamed up with Su Xiaoyu to cultivate suitable fish fry, Lin Hetang to manage the water surface, He Xiaowang to be responsible for catching fish, and Zhou Xiaou to process lotus root starch. With the bumper harvest of both lotus roots and fish, e-commerce and tourism gradually opened up markets. When heavy rain flooded the pond, He Yuemang led the villagers to drain the water overnight, the veteran lotus farmer relied on years of experience to save the lotus pond, and He Laotang completely approved of the new model. Finally, the lotus root festival was successfully held, lotus root-fish co-culture was fully promoted in Lotus Pond Village, young people returned to their hometowns, and the lotus pond once again became a new paradise for villagers to stably increase their income.
