A woman who visited the Ning family's home. She was suffering from insomnia and felt awful before drinking the herbal tea and lotus stamen tea brewed by Ning Xin. After the tea, she felt clear-headed, refreshed, and was able to sleep soundly. She left a total of six yuan (one yuan initially plus five yuan in a handkerchief bundle) as a thank you gift, far more than the cost of the tea and meal.
