At the age of five, Zhang Haidi suffered from spinal hemangioma and paraplegia. Because of this, she has never been to school. From an early age, she began to teach herself knowledge with tenacious perseverance. She taught herself specialized courses in primary schools, middle schools and universities. When Zhang Haidi was fifteen years old, she was sent to a poor village in Shen County, Liaocheng with her parents. But she is not afraid of hard life, but dedicated her youth with optimism. There, she taught the children in the village primary school, overcame all kinds of difficulties to learn medical knowledge, and enthusiastically treated the villagers with acupuncture. During her stay in Shenxian County, she treated more than 10,000 people for free and was warmly praised by people.
