Plot: Sandstorm, waterlogging, salinity and other "three evils" plague Lankao area, and Jiao is appointed as the county party secretary here by his superiors. In order to eradicate the "three evils" and help the masses get rid of poverty and become rich as soon as possible, Jiao made an in-depth investigation immediately after arriving in Lankao, and formulated a treatment plan. However, when the relief materials arrived in Lankao, Jiao took the initiative to lead the county party committee cadres to the railway station to unload and deliver the goods. Wu Rongxian, deputy secretary of the county party committee and county magistrate, was indifferent and dissatisfied with the leadership work in focus. The old director of the county gardening field was exhausted, and Jiao was very shocked. He decided to increase the ration of grassroots cadres, but someone complained to the prefectural party Committee at the instigation of Wu Rongxian. The superior came to understand the situation, and hundreds of people blocked the door of the conference room, which was unfair for Jiao Ming. Soon, Lankao was once again hit by a devastating flood, and Jiao endured liver pain and rushed to the front line of emergency rescue and disaster relief. However, due to long-term overwork, Jiao's liver disease continued to deteriorate, and he died in the early morning of May 1964 at the age of 42. His body was buried in the sand dunes of the old course of the Yellow River, and nearly 100,000 people spontaneously held a funeral for him to express their love and nostalgia for this good secretary.
