Bai Shizhou, who majored in clinical medicine, was a medical student trained by the state. He went to Xiancao Village to work as a rural doctor. Li Changsheng, an old Chinese medicine doctor in the health center of Xiancao Village, has been practicing medicine for generations and is well-known far and wide. Two doctors, one old and one young, started a battle between Chinese and Western medicine in a health center. Gradually, Bai Shizhou discovered that although the Chinese medicine he despised was slow to take effect in the short term, it could cure the root cause and form a good complement with Western medicine. Li Changsheng also realized that common chronic diseases in rural areas can only be more effective under the combined treatment of Chinese and Western medicine. From then on, the two doctors, one old and one young, one Chinese and one Western, abandoned their prejudices, integrated Chinese and Western medicine and helped each other, and treated the villagers together, becoming the patron saint of rural health. While curing diseases and saving lives, Wang Yanan, a college student village official, discovered a good opportunity to get rich. He provided technical guidance to the villagers to grow medicinal materials and sell them nationwide, which was well received by the market. Xiancao Village gradually achieved the goal of a well-off society. After three years of career as a rural doctor, Bai Shizhou not only fell in love with every tree and blade of grass in Xiancao Village, but also fell in love with Wang Yanan here. He decided to stay in Xiancao Village and continue to protect the safety and health of the villagers with Li Changsheng.
