A gentle knock on the door sounded on the door of the second-year high school Chinese office. Several teachers working in the office raised their heads from behind the desk. They saw a middle-aged woman in her thirties standing at the door. She was wearing a beige medium-length windbreaker, a small floral long silk scarf, a black turtleneck sweater and a light brown mid-skirt. She was flesh-colored leggings and tights on her legs. She wore a flat purple leather shoes. She dressed up with a mature woman's charm. She had a good figure and was not said to be a black sweater that could not cover her plump breasts. Her lower abdomen was flat, not like other middle-aged women who were fat. The two calves exposed outside the skirt were even straight and slender, which was fascinating. She had beautiful and charming appearance, big eyes, thin eyebrows, a cherry mouth, a firm nose bridge, and a simple makeup that was beautiful.
