He casually answered her question that morning, and Jiang Yao memorized Mrs. Lu's problem with arthritis. The first thing she did when she arrived at the county was to go to the pharmacy to get medicine, and the first thing she did when she returned was to go to the kitchen to prepare the medicine. Then, she guarded the kitchen for more than 40 minutes.
If she did not care about Mrs. Lu, if she did not have enough patience, she would not have done all those things.
Jiang Yao crouched beside Mrs. Lu's feet and applied the medicine on her legs. In Mrs. Lu's eyes, Jiang Yao was not a doctor but her own child.
Mrs. Lu was satisfied even if Jiang Yao could not cure her arthritis.
