The smoke of the Anshi Rebellion has not yet dissipated. Li Mingyuan took canal water and rice seeds to sow hope in the land of Huaixi. In the troubled times of feudal rule, he used water conservancy as his blade and farming as his armour, allowing the Huaixi Canal to flow from north to south, occupying the city and filling the Central Plains with green rice. From Hebei to Hexi, wherever the canals overflow, fighting gives way to hoeing and plowing; when the ears of rice hang low, the hearts of the people gather to form the Great Wall. This is not an epic story about princes and generals, but the perseverance of a porridge and a meal - the original password to bring peace to the world is hidden in the new rice held up by the people.
