Yang Jinghai had already decided to close up shop and no longer provide medical consultations. He dedicated himself to caring for Liu Xiaoyu and teaching Tang Huai the art of medicine.
When Old Lady Jing came to seek medical assistance, the temperamental Yang Jinghai, of course, refused.
Yang Jinghai was capricious, and Old Lady Jing had a fiery temper; it didn't take long for an argument to erupt between them.
For a traditional Chinese medicine practitioner, was there really a time to "close up shop"? Wasn't it "treat until your last breath"? If he was closing up shop, why was he still treating Liu Xiaoyu?
Old Lady Jing had no idea that the reason Yang Jinghai was so intent on taking good care of Liu Xiaoyu was that he saw her as a daughter-in-law and her child as his grandchild.
He now considered them part of his family; naturally, he felt obliged to look after them.
