In the Tang Dynasty of China, there was a famous doctor in Shaanxi named Sun Simiao (581-682). He was good at treating various difficult and complicated diseases and saved many dying patients. He lived to be 101 years old, and history called him the "100-year-old miracle doctor." One day, four people were carrying a coffin, and blood was dripping from the bottom of the coffin. Sun Simiao thought that the person was not dead yet, so he asked them to open the coffin. They saw that the deceased was a woman. Sun Simiao felt her pulse and then selected an acupuncture point for injection. After a while, a fat baby fell to the ground, and the woman came to life. Sun Simiao saved two lives with one injection, and people called him a miracle doctor! Once, a patient couldn't urinate and begged Sun Simiao to save him. Sun Simiao concluded that his urinary outlet was blocked. At this time, there happened to be a child playing with an onion tube and blowing on it. He asked for the onion tube to cut off the tip, carefully inserted it into the patient's urethra, and blew hard, and the urine flowed out along the onion tube. This bold experiment actually made him the first person in the world to invent urinary catheterization. Sun Simiao was not only good at medicine, but also good at nutrition. He compared beriberi and night blindness to study treatments. At that time, many poor people in the mountains suffered from night blindness, while the rich suffered from "beriberi". Sun Simiao compared the two diseases and thought that they were definitely caused by nutritional problems. The poor people ate a lot of glutinous vegetables, so I asked them to eat more animal livers, and it really worked. Rich people lack nutrients such as rice bran and bran, so they ask patients with athlete's foot to eat more whole grains, and the results are also effective. He became the first person in the world to treat beriberi. Sun Simiao was also good at acupuncture and created the acupuncture method of "selecting acupuncture points based on pain". Once he gave a patient with leg pain an injection, but several injections had no effect. While he asked the patient where it hurt, he gently pinched it down along the thigh with his hand. When he pinched the painful spot, the patient couldn't help but screamed: "Ah... yes." Sun Simiao immediately inserted a needle at this place, and the patient's My legs no longer hurt immediately. This point is not in medical books, so Sun Simiao called it "Ashi point". Sun Simiao is also known as the "King of Medicine". In order to collect herbs, he traveled to famous mountains and rivers and processed the crude drugs himself. During his long-term medical practice, he extensively collected and compiled many prescriptions. When he was 70 years old, he compiled and compiled these prescriptions into "A Thousand Gold Prescriptions". Another 30 years later, when he was already a centenarian, he still compiled the prescriptions accumulated in the next 30 years into "Qian Jin Yi Prescription". These two books recorded more than 6,000 prescriptions and became classics of traditional Chinese medicine. He carved some major medicinal prescriptions on stone tablets and erected them at major intersections or streets, which played a very good role in treating and preventing diseases. People called Mount Wutai, where he often went to collect medicinal herbs, "Mt. Medicine King." Later, the masses built a Yaowang Temple in Yaowang Mountain to commemorate this 100-year-old miracle doctor.
