My sister-in-law, what's wrong with my sister-in-law? Who touched my sister-in-law? At the southern end of the ancient city stands a small courtyard of the Sun family. Like all the households, the Sun family also has its own unspeakable troubles. Sister-in-law Fan Huimin is nearly forty years old and works as the sales department director at an electrical appliance mall. Her husband Sun Haiqiang works in geological work and stays outside for a long time. As the elder sister-in-law of the Sun family, all the complicated household affairs fall on her shoulders. He Lin, her sister-in-law who works at the same mall, often takes sick leave to engage in pyramid selling, argues with customers, and causes trouble for her sister-in-law.
