90-year-old tuberculosis expert Ma Yue, who has been a doctor for 67 years, still insists on visiting every week. Every time she sees a doctor, she will heat the stethoscope first; record the handwriting of the disease, always neat; if other diseases are found during the examination, she will also take the initiative to find the patient, “don’t look for it, it will delay things”. #90-year-old doctor said that he has no regrets when he thinks of a cured patient#: “He was cured in the past, and the patient sent me a letter 58 years later. This is the highest reward to me.”
