Botany boss Qi Shutong accidentally transformed into the young daughter of Qingxi brigade boss Qi's family who had just recovered from illness, and became the group favorite of her three brothers. Seeing that villagers had abandoned farming due to lack of water, she combined modern knowledge and first used "local methods" to improve breeding and increase wheat harvest, winning the trust of the commune. Then, referring to the Xiangdong Canal's "local materials" experience, we designed a stone-gong water canal plan and led the villagers to dig mountains and open canals. In the process, problems such as stone shortages and measurement deviations were solved, and the project even teamed up with neighboring villages to build an aqueduct. During this period, he partnered with Qu Yanshen, a water conservancy technician who had returned from the army. With the full support of his family, he not only turned thousands of acres of dry land into fertile farmland, but also piloted greenhouse vegetable cultivation, helping the entire village escape poverty, and eventually became the commune's "infrastructure leader."
