On November 3, 2023, his mentor, Academician Wang Zhonghao, passed away suddenly at the age of 86. Fellow vascular surgeons across the country, thousands of patients who had been treated by him, and many disciples at home and abroad were all plunged into endless grief. When the bad news came, I was performing a complex aortic aneurysm surgery at Fuwai Hospital, and the scalpel in my hand suddenly became heavy. Having followed his mentor for nearly thirty years, his lifelong dedication to medicine and his dedication to saving patients are vivid in his mind and linger in his heart. Just two days before my mentor passed away, I went to visit him in the ward. Although he was in weak health at the time, he still told me to go home early so as not to delay my clinical work the next day or delay the patient's treatment. Unexpectedly, a few words could become an eternal secret. Heaven and man are forever separated, and the thought of it brings tears to my eyes.
