idk about bao sanniang, never heard of them before

oh, i guess she's in the book too since she's his wife

Bao Sanniang (onyomi: H Sanj) is the third daughter of the Bao family and is known as one of Guan Suo's wives within fiction. She originated from the Hua Guan Suo Zhuan, a tale in which Guan Suo is the main protagonist and instead known as Hua Guan Suo. Proud of her warrior training, she refused marriage until he defeated her in a duel. Her character is considered a direct homage to Hu Sanniang, a character from the novel, Water Margin, who met her husband in a similar manner.
