Since the founding of New China 60 years ago, with the changes of society, many changes have taken place in people's sports. This newspaper's "Large-scale Image Collection of 60th Anniversary of the Founding of the People's Republic of China" has collected many photos of people's sports scenes in different periods, and many readers have recorded people's love for sports from 1950s to 1970s with a unique perspective. Looking at the photos and recalling the past, we can also see the characteristics and life background of each era. Broadcast gymnastics at the entrance of the cinema In the early days of the founding of the People's Republic of China, sports was regarded as an integral part of national construction and was included in the fundamental law of the country. 1949 In September, on the eve of the founding of People's Republic of China (PRC), the People's Political Consultative Conference of China adopted the same program, clearly stipulating "promoting national sports". Although life was still very poor at that time, love of labor, love of sports, hard work and vigor became the spiritual outlook of the whole society. In an old photo 1952 taken by Zhao Qinghua, an old photographer, the workers in Jiefang Cinema are doing broadcast gymnastics uniformly in front of the rising sun, and there are people leading the team in front. In response to Chairman Mao's call of "developing sports and strengthening people's physique", the employees of the No.1 automobile repair shop in Gansu Province used their brains to make many barbells with old automobile parts. In their spare time, workers gather in the yard to lift weights and exercise. 1970, An Yang, an employee of No.1 Auto Repair Factory, used his newly bought camera to leave such a picture: shirtless workers are lifting weights in front of the factory building, and their movements are skilled and standard, and barbells made of automobile bearings and gears are clearly visible. Looking back now, Chen Huan' ang, who has retired, is filled with emotion: "At that time, the conditions were not good, and people tried their best to make all kinds of sports equipment. Now there are more types of fitness equipment, but fewer people exercise. " Simple swimming pool holds water sports meeting. In the 1970s, although sports facilities were rudimentary, there were still many mass sports. On July 1972 and 1 day, in Yantan's humble swimming pool, people who love sports held a water sports meeting here, which was a grand event. In the photo taken by Lao Zhaoman Tsinghua, three athletes performed on three platforms with different heights. The movements of take-off, volley and entry were neat and elegant, and onlookers crowded the stadium. Zhao Qinghua also filmed the children's track and field games in Qilihe area on 1972. The team that entered the stadium walked past the rostrum holding the portrait of Chairman Mao and the slogans of "Long live Chairman Mao" and "Glory for the great leader Chairman Mao". In another photo, 1974, the policewoman of Dunhuang road police station is holding the "five spring arms", which is very heroic.
