During the period of Premier Zhou Enlai in the 60s, Chinese men's middle-distance running began to emerge. At that time, many athletes such as Dong Xuesheng and Deng Yaping shined and gradually achieved good results in the Beijing International Marathon, National Track and Field Championships and other events. Among them, the 5000m record (13:51.38) held by Yin Baozhen has not been broken so far.
