Hearing this, Yan Shu subconsciously straightened her back.
Mu Qingli reached out to open her shoulder blades, correcting her posture, "Like this, chest out, stomach in, head up, right, keep the waist straight, and hold it."
Yan Shu followed her instructions.
Mu Qingli nodded with satisfaction and took Yan Shu's hand, "Come with me over here."
Mu Qingli led Yan Shu to a full-length mirror and smiled, "Do you see how the person in the mirror is different from before?"
Yan Shu lifted her eyes to look.
In the mirror, the person's face bloomed like a peach blossom, her eyes seemingly speaking, her posture upright, her aura in full bloom in an instant.
Compared to the person she was before, who hunched her head and whose entire forehead was hidden by thick bangs, it felt almost like two different beings. In that moment, Yan Shu finally understood the true meaning of the textbook phrase "Stand like a pine, sit like a bell."
