An ordinary water spring turned into a lake (paozi) overnight. Through the origin and disappearance of Paozi, it describes a myth and legend in which the "golden dragon" and the "silver dragon" ensure a smooth life and are unwilling to be slaves to the subjugation of the country. The Taoist Priest's selfless help, Shopkeeper Li's benevolent deeds, and Taoist Zhou's conscientiousness are all amazing in the book! In particular, Ma Baochang's transformation from believing in feudal superstition to an outstanding Communist Party member is even more impressive.
