Mr Zhang Boli, academician of China Academy of Engineering and president of Tianjin University of Traditional Chinese Medicine, commented: "He Lao is my most respected teacher and elder. In the early 1970s, I worked as an intern with He Lao in Children's Hospital for three years, and later I specialized in encephalopathy with He Lao in the Department of Encephalopathy of Tianjin Hospital of Traditional Chinese Medicine. I will never forget these two experiences. He Lao is knowledgeable, teaching Chinese medicine theory is simple and unique, vivid and humorous, and it is my favorite class. It is very kind to copy the internship with him, and the key points are always unreserved to make comments and suggestions. He Lao taught and educated people all his life and was willing to be a ladder. The level and strength of traditional Chinese medicine in Tianjin are inseparable from He Lao's years of work, and he is an indispensable symbol. He Lao enjoys a high academic status in the field of traditional Chinese medicine in China, with profound theoretical foundation, rich clinical experience and broad vision. He is a model of medical ethics and a master of medical skills. He is a scholar with outstanding achievements, an advocate and practitioner of integrated traditional Chinese and western medicine, and one of the founders of the theoretical system of new medicine in China. In particular, he has made great, outstanding and historic contributions to the theoretical and clinical academic research of encephalopathy in traditional Chinese medicine. He Lao's medical heritage and spiritual heritage should be excavated and sorted out comprehensively, deeply and rescuedly, and should be inherited, carried forward and carried forward. "
