Taking the life of the lower class in the Song Dynasty as the core, and through the perspective of an "atypical" protagonist, it depicts a vivid, lively and absurd Jiangnan style painting of the Song Dynasty. The core of the story lies in "subversion" and "collision": the cultural collision between a military attache from a provincial capital who is in the military but wants to "lie down" and a small village around Poyang Lake with simple folk customs and full of survival wisdom; the dramatic conflict between the thinking logic of modern people and the social rules of the Song Dynasty. The novel will abandon the traditional routine of heroism, and use jokes derived from life details throughout the book to connect the protagonist's various adventures in settling down in Duchang and integrating into the countryside, and gain a glimpse of the real operating logic and people's livelihood of the grassroots society of the Song Dynasty through laughter.
