A certain modern "cow horse" accidentally wore a book and became the "evil sister-in-law" that everyone hated. Faced with the glare of the whole village and the best relatives, she put away her original arrogance and used her medical skills and business acumen to create a clear sky in the muddy mountain village. The "scourge" that everyone could avoid originally became the backbone of the family and the "lucky star" of the whole village. This is a growth story about letting go of prejudice and using your skills to win respect.
