Sixty-eight years ago today, on November 17, 1957 (September 26, 1957), our country's athlete Zheng Fengrong set the world record for women's high jump. Zheng Fengrong jumped 1.77 meters at the Beijing Athletics Games, which was the first time our country's athletes broke the world record in track and field. At 11:23 am on November 17, 1957, Zheng Fengrong (now 20 years old, 1.70 meters tall) participated in the women's high jump competition of the Beijing Games at the Xiannongtan Stadium in Beijing. He jumped 1.77 meters, breaking the world record of 1.76 meters set by the black American athlete McDaniel in Melbourne on December 1, 1956 and held for less than a year. This is the third person in our country to set a world record after Chen Jingkai and Qi Lieyun. On November 17, Zheng Fengrong, wearing white shorts, made about half an hour of preparations and jumped the first height she asked to jump very easily with the "scissor" movement - 1.56 meters. Then, she jumped 1.60 meters, 1.64 meters, 1.68 meters and 1.72 meters in height. When the cross pole was raised to 1.77 meters, she did not jump for the first time because her step point was not accurate. However, she finally succeeded in her second attempt to jump. Zheng Fengrong jumped the height of 1.70 meters and above eight times in 1957. No other female athlete in the world can jump such heights so many times in a year. Zheng Fengrong loved sports since she was a child and often competed in high jump with her little brother. In 1953, she was selected to the track and field team of Shandong Province and participated in the National Games. For the first "expedition", she achieved a result of 1.36 meters. This result was only 4 centimeters short of the national record at that time, which made her very happy. This year, she was admitted to the Beijing Institute of Physical Education. There she began a systematic and step-by-step comprehensive physical exercise. The result soon improved to 1.45 meters. But later, she suffered severe arthritis due to a leg injury caused by practicing long jump. By the time her health was fully restored, two years had passed. When she returned to the track and field, she could not jump over the height of 1.40 meters. Faced with difficulties, she had become passive, and she planned to stop practicing high jump and change to javelin. Later, with the encouragement and help of teachers and classmates, she mustered up her courage and resolutely embarked on the journey of hard exercise. On the way forward, she encountered new difficulties. It turned out that the posture she used for high jump was a backward leap. So she began to change to scissors. But changing positions is not an easy task, because if you don't get it right, your grades will be reduced. It turned out that her grades did drop again, but she was not discouraged. She felt that the people around her were supporting and encouraging her. She followed the teacher's instructions and practiced again and again with enthusiasm. Every day, in addition to the comprehensive exercise of ball games, gymnastics, track and field, she also performed about 100 high jump exercises, and also used various auxiliary movements to correct the high jump movements. Her grades gradually rose from 1.40 meters, and in the summer of 1957, she created an excellent result in the GDR - 1.72 meters. At the National Track and Field Games held at the Wutai Mountain Stadium in Nanjing in October 1957, she jumped 1.73 meters, and a few days later in Shanghai, she jumped 1.74 meters. On November 3, she jumped another 1.75 meters in Beijing. Zheng Fengrong, a famous high jumper in the 1950s, Zheng Fengrong
