Zhang Qigui, 91, is a doctor of Chinese traditional medicine. Donating his whole body has been his plan all along. "No doctor didn't use samples of the human body during his education. It is impossible for us to grasp the knowledge without the help of the deceased. Now, my remaining years are not many. Donation of my body is what I plan to do. I hope it is helpful."
