She Looked Down on Me, Unaware I’m the Madam

During a public calligraphy class, a mother slaps the teacher for a child writing one crooked character and relentlessly bullies her, relying on her husband’s high position in a powerful group. She has no idea the modest teacher she despises is actually the wife of the group’s president. When the couple’s crimes of stealing core secrets, nearly killing their asthmatic son through superstition, and attempting extortion are exposed, their arrogant world collapses completely. Some parents end up teaching the harshest lessons to themselves.
