Su Wan just married into the Hou Mansion, which has strict rules, and her mother-in-law Shen Jingshu conducted strict "job training" for her. Su Wan relied on modern emotional intelligence and observation skills to discover that her mother-in-law had superb management skills but was not happy. Some details (such as accounting methods and dealing with unruly slaves) revealed neatness and wisdom beyond the times.
Su Wan inadvertently used modern simple drawing methods to improve the complicated utensils album in the house, which was seen by her mother-in-law. Shen Jingshu denounced "strange skills and obscene skills" on the surface, but she was lost in thought in the album alone late at night. Su Wan captured this moment and realized that her mother-in-law was not a decadent feudal symbol, but a smart person buried by the times.
When the family encounters a crisis (such as being framed by a business rival or making mistakes in important accounts), Su Wan uses modern crisis public relations and logical deduction to help her mother-in-law solve the problem perfectly in private. Shen Jingshu was shocked by her vision and skills. For the first time, she let go of her guard, and the two had a conversation under the moonlight that transcended the status of mother-in-law and daughter-in-law. The alliance was first established.
