Zhang Haidi

After undergoing cancer surgery in 1991, Zhang Haidi continued to fight against fate with an unyielding spirit. She began to study postgraduate courses in philosophy. After unremitting efforts, she wrote the paper "Disability Issues from the Perspective of Cultural Philosophy". In 1993, she passed the postgraduate course examination and thesis defense in the Philosophy Department of Jilin University and was awarded a master's degree. Zhang Haidi proved the power of life with her own courage. Just as she said, "Like all people who are determined, I regard the arduous inquiry itself as true happiness." She uses the spirit of overcoming her own obstacles to help disabled people A path opens up into the ocean of knowledge.

Zhang Haidi has also done a lot of social work over the years. She has inspired countless young people to work hard with her speeches and singing. She also often goes to orphanages, special education schools, and disabled families to visit orphaned elderly people and disabled children, sending them gifts and warmth. In recent years, she has built a primary school for the villages where she went to the countryside, helped poor and disabled children with medical treatment and education, and also donated more than 60,000 yuan of her royalties to disaster-stricken areas and children. She also actively participated in various work and activities for the cause of the disabled, calling on the whole society to support the cause of the disabled, care for and help the disabled, and encourage them to become self-reliant. Supporting the cause of disabled people, caring for and helping disabled people, encouraging them to become self-reliant, and making outstanding contributions to the development of the cause of disabled people.

Tong Dizhou

Member (academician) of the Chinese Academy of Sciences, biologist, educator, and one of the founders of experimental embryology research in China . He once served as vice president of Shandong University, first director of the Institute of Oceanography of the Chinese Academy of Sciences, vice chairman of the Chinese Marine and Limnological Society, director of the Department of Biology of the Chinese Academy of Sciences, vice president of the Chinese Academy of Sciences, vice chairman of the National Committee of the Chinese People's Political Consultative Conference, director and professor of the Department of Zoology of Shandong University, etc. job.

Tong Dizhou is a famous biologist in my country and an internationally renowned scientist. He has been engaged in experimental embryology research for nearly half a century and is the main founder of experimental embryology in my country.

Tong Dizhou was born in a remote mountain village in Yin County, Zhejiang Province. Due to a poor family, he studied cultural knowledge from his father when he was a child. He did not enter school until he was 17 years old.

When he was in middle school, due to his poor foundation, he struggled to study. At the end of the first semester, his average score was only 45 points. The school ordered him to drop out of school or repeat a grade. After his repeated requests, the school allowed him to study with the class on a trial basis for one semester.

Since then, he has always been with the "street lamp": at dawn, he read foreign languages ????under the street lamp; after the lights were turned off at night, he repaired himself under the street lamp. Hard work paid off. By the end of the semester, his average score reached more than 70 points, and he scored 100 points in geometry. This incident made him realize a truth: I can do what others can do through hard work. There is no genius in the world, and genius is obtained through labor. After that, this became his motto.

After graduating from university, he went to study in Belgium. While studying abroad, Tong Dizhou studied hard and was diligent and studious, which was highly praised by his teachers. After receiving his doctorate, he returned to his disaster-ridden motherland and conducted scientific research under extremely difficult conditions.

Without electric lights, they used natural light to cut and separate eggs under a microscope in a dark yard; without glassware for culturing embryos, they used stoneware wine glasses instead, and used microdissection techniques. The instrument is just a very thin glass fiber that I pulled myself; the frog eggs used in the experiment were all collected from the wild. In this simple "laboratory", Tong Dizhou and his colleagues completed several papers on the analysis of the development ability of goldfish eggs and the analysis of the ciliary movement mechanism of frog embryos.

After liberation, while Tong Dizhou served as vice president of Shandong University, he studied the development rules of amphioxus eggs, which play an important role in biological evolution, and made great achievements.

In his later years, he collaborated with Professor Niu Manjiang of Temple University in the United States to study the relationship between the nucleus and the cytoplasm. They extracted a nucleic acid from the cytoplasm of crucian carp eggs and injected it into the fertilized eggs of goldfish. The results An offspring with both goldfish and crucian carp traits appeared, and the tail fin of this goldfish changed from a double tail to a single tail. This kind of creative achievement ranks among the advanced in the world.

Reasons for success:

(1) Perseverance to fight hard

(2) Perseverance and character

(3) A positive and optimistic mood

(4) A fearless spirit that is not afraid of difficulties
