Sun Yunwei was originally named Sun Hua. Born on January 10, 1908 in Wujiang County, Jiangsu Province. Her mother lost her mother at the age of 12 and was raised by her brothers and sister-in-law.

In 1928, he graduated from Suzhou Agricultural School. Due to his family's financial difficulties, he did not continue his studies. He went to Nanjing Zhongshan Cemetery as a technician and managed more than 500 acres of orchards and vegetable fields. He worked there for more than three years and accumulated rich experience in fruit and vegetable production. During this time, he successively wrote six popular science books on horticulture, including "Tomato and Strawberry Cultivation Method" and "Latest Watermelon and Lily Cultivation Method". In 1932, he traveled to Japan with the manuscript fee for publishing three books and the support of his brother and sister-in-law, and studied at his own expense.

He came to Japan's National Horticultural Experiment Ground, studied hard, worked hard, and learned many new techniques, such as watermelon grafting techniques, strawberry cultivation and hillside cultivation techniques using solar hot stone walls, mushroom breeding techniques, etc. He wrote these new techniques into articles and sent them back to China for publication, which was well received by domestic readers. In April 1934, he returned to China due to economic difficulties. In April 1935, he went to Japan for the second time at his own expense at the Horticultural Research Laboratory of the Department of Agriculture of Kyushu Imperial University (now Kyushu University) to systematically study the theory and cultivation techniques of Japanese fruit tree horticulture, and inspected Hokkaido University and Aomori Apple Experiment Ground. He returned to China in June 1936.

After returning to China, he successively worked in Qingdao Agriculture and Forestry Office, Qingdao Fruit Production Company, and Shanghai Fruit Inspection Office. In January 1940, he moved to Beijing to serve as the director of the Beijing Horticultural Experimental Ground. He was mainly engaged in the cultivation of fruit trees, vegetables, flowers, and the promotion of fruit seedlings and seeds, as well as the rectification and construction of the entire site. He served as a counselor and deputy director of the deliberation department of the North China Fiber Control Federation, which was occupied by the Japanese invaders at that time, specializing in technical work. In May 1945, he went to Qufu Agricultural College in Shandong Province to lead the preparatory work, and soon he went to Hangzhou China Agricultural Products Company as the chief technician and farm director. In January 1947, he served as a professor in the Department of Horticulture at Northwest Agricultural College, and in July 1948, he served as a professor at the School of Agriculture at Zhongzheng University in Nanchang.

Nanchang was liberated in May 1949, and he went to Nanchang's August 1st Revolutionary University to study. This study became a "turning point in his life." He said: "Intellectuals from the old society can only play their due role under the leadership of the Communist Party..." At that time, someone offered him a plane ticket to Taiwan, but he flatly refused.

In the winter of 1949, he returned to Northwest Agricultural College as a professor and head of the Department of Horticulture. He felt fortunate to be in a prosperous era and actively participated in fruit tree teaching, scientific research, editing and production technology promotion. In 1950, he joined the China Democratic League. In 1962, he joined the Communist Party of China. He was elected as a deputy to the Second and Third National People's Congress of Shaanxi Province. He served as a member of the Shaanxi Provincial Association for Science and Technology, and the chairperson and honorary chairperson of the Shaanxi Provincial Horticultural Society.
