The story of Zhou Junyi's crossing the Grand Canal in Changzhou is: During the Tang Dezong period in the Tang Dynasty, Tang Dezong built the Grand Canal to transport grain in Changzhou due to lack of grain. At that time, the bodies of starving people were everywhere. When they saw the grain and grass escorted by Zhou Junyi, the people immediately shouted, "Rice has arrived in Shaanxi, and my father and son are going to live."
