Su Wenwu wanted to see his sister's excited expression, but he did not expect her to be so calm. It was as if she was used to it. No, his younger sister was just confident in her medical skills.
"Sister, I passed by Old Madam Lin's house when I returned to the village. She was picking vegetables at the door and said she had slept well last night. Her legs no longer hurt, and she didn't wake up because of the pain.
"She said your prescription was effective. She didn't expect to be able to buy such good medicine at such a low price. She asked me to thank you on her behalf."
Su Wenwu was thrilled. "Old Madam Lin said her legs used to hurt a lot whenever it got cold, and she couldn't even sleep because of the pain. Last night, she applied the medicine to her legs and drank your prescribed medicine, so she slept soundly. She's pleased."
