Lei Feng, formerly known as Lei Zhengxing, 1940 was born in a poor peasant family in Wangcheng County, Hunan Province.
1In August, 949, when Hunan was liberated, Feng found the passing company commander of the People's Liberation Army and asked to be a soldier. The company commander disagreed and gave him a pen. From 65438 to 0950, Lei Feng became the leader of children's group and took an active part in land reform. In the summer of the same year, the township government accompanied him for a walk and study for free, and later joined the Young Pioneers. 1956 summer, worked as a correspondent in the township government after graduating from primary school, and soon transferred to Wangcheng County Committee as a civil servant, and was rated as a model worker of the government. He joined the league on 1957. 1958 In the spring, Lei Feng went to Tuanshanhu Farm and learned to drive a tractor in only one week. In September of the same year, Lei Feng responded to the call to support Angang and went to Anshan as a bulldozer. In August of the following year, he came to Gongchangling Coking Plant to participate in infrastructure construction, led his partners to fight in the rain, and saved 7,200 bags of cement from loss. Liaoyang Daily reported the story at that time. During my work in Anshan and Coking Plant, I was rated as an advanced worker for three times, a pacesetter for five times, a red flag bearer for 18 times, and won the honorary title of "Young Socialist Construction Activist".
1959 12 At the beginning of conscription, Lei Feng urgently requested to join the army, and the leaders of the coking plant were reluctant to let him go. Lei Feng ran dozens of miles to the Liaoyang Military Service Bureau (now the People's Armed Forces Department) to show his determination to join the army. He is only 1.54 meters tall and weighs less than 55 kilograms. None of them met the recruitment requirements, but because of his excellent political quality and rich technical experience, he was finally approved to join the army as an exception.
During the War of Resistance against Japanese Aggression period, a famous anti-Japanese hero appeared in Moyuan County, Hebei Province. His name is Wang Erxiao. Wang Erxiao was only seven years old when he died. When the Japanese army swept a ravine, he took the enemy into the ambush of the Eighth Route Army in order to cover thousands of villagers and cadres, regardless of his own life. Angry Japanese picked Wang Erxiao with a gun and fell to death on a big stone. Cadres and fellow villagers were out of danger, and the little hero Wang Erxiao died heroically. Wang Erxiao's touching story soon spread all over the liberated areas, and every fellow villager sang "Two Little Boys and Cowboys" with tears in his eyes. Shanxi-Chahar-Hebei Daily reported Wang Erxiao's heroic deeds on the front page. In the literary and artistic war in the Shanxi-Chahar-Hebei border region, Tu Bing and hijackers quickly created the famous children's song "Singing Two Little Boys and Letting the Cowherd Go", which was later sung all over China.
Tong Dizhou, an academician, biologist and educator of China Academy of Sciences, is one of the founders of experimental embryology research in China. He used to be the vice president of Shandong University, the first director of Institute of Oceanography of China Academy of Sciences, the vice president of China Ocean and Lake Society, the head of biology department of China Academy of Sciences, the vice president of China Academy of Sciences, the vice president of Chinese People's Political Consultative Conference, and the head and professor of zoology department of Shandong University.
Tong Dizhou is a famous biologist in China and an internationally renowned scientist. He has been engaged in experimental embryology for nearly half a century and is the main founder of experimental embryology in China.
Tong Dizhou was born in a remote mountain village in Yinxian County, Zhejiang Province. Because of his poor family, he studied cultural knowledge with his father since childhood and didn't enter school until 17 years old.
When he was in middle school, he studied very hard because of his poor foundation, and his average score at the end of the first semester was only 45 points. The school ordered him to drop out of school or repeat the grade. After his repeated requests, the school agreed to let him try out with his class for one semester.
Since then, he has been with the "street lamp": at dawn, he reads a foreign language under the street lamp; After turning off the lights at night, he learns to review himself under the street lamp. Many things happen. At the end of the term, his average score reached more than 70, and he also got 100 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, genius is bought with labor. After that, it became his motto.
After graduating from college, he went to Belgium to study abroad. During his study in Tong Dizhou, he studied hard and was eager to learn, and was well received by his teachers. After receiving his doctorate, he returned to the disaster-stricken motherland and conducted scientific research under extremely difficult conditions.
Without electric lights, they cut and separate eggs with natural light under a microscope in a dark yard; There is no glassware for cultivating embryos, so we use coarse porcelain pottery wine glasses instead, and the micro-dissector used is just a very thin glass filament pulled by ourselves; The materials used in the experiment are all frog eggs collected from the field. In this simple "laboratory", Tong Dizhou and his colleagues have completed many papers on the developmental ability of golden croaker eggs and the analysis of the ciliary movement mechanism of frog embryos.
After liberation, Tong Dizhou, as the vice president of Shandong University, studied the development law of Wenchang fish eggs, which played an important role in biological evolution, and made great achievements.
In his later years, he cooperated with Professor Niu Manjiang of Templeton University in the United States to study the relationship between nucleus and cytoplasm. They extracted a nucleic acid from the cytoplasm of crucian carp eggs and injected it into the fertilized eggs of goldfish. As a result, a descendant with the characteristics of both goldfish and crucian carp appeared, and the tail fin of this goldfish changed from double tail to single tail. This creative achievement belongs to the advanced level in the world.
