A girl has been feeling chest tightness and difficulty breathing recently. Her mother was worried, so she took her to see a Chinese doctor. After observing, smelling, asking and palpating, the doctor asked her: "Is your chest tightness obvious during the day, but not at night?" She thought about it and thought it was, so she answered "yes". Her mother asked hurriedly: "What's wrong with the child?" The old man adjusted his glasses, looked up at the girl and said: "The bra is too small!"
