In an unknown town on the edge of the rivers and lakes, there is an inn that can turn "martial arts" into a "joke" - Juqi Lou.
The shopkeeper Jin Yuanbao, the daughter of a Beijing silk and satin shop, ran away to open an inn. He is better at calculating abacus than anyone else, but he always calculates "profit of three taels" as "loss of five taels" when calculating accounts. The abacus studded with fake gemstones can be swung louder than a kitchen knife, all because of his imposing manner; the waiter Li Xiaodao, who calls himself "The descendant of the Flying Knife Sect", the throwing knives never hit the target, but they always hit the shopkeeper's new clothes accurately. The material for bragging is all from the story book; the cook Sun Erniang (male), a pretty face with the name of "Dominatrix", always hums off-key ditty when cooking, and specializes in the dish "Half-Step Ding with a Smile" In fact, it's Mapo Tofu with too much peppercorns, which can make people laugh until their knees weaken after eating it; Lin Moying, the accountant, is a former disciple of the God of Thieves but is always betrayed by his own shadow. He can calculate how many pennies the guests have lost, but can't calculate how much the inn has lost;
This is not a serious martial arts, but a group of "unreliable" people, making a lot of ridiculous jokes in an inn that "could collapse at any time".
