Zhoukoudian site is located 50 kilometers to the southwest of Beijing. It was one of China's first batch to be inscribed in the List of World Heritage Sites by the UNESCO back in 1987. In 1929, skull fossils of the Peking Man were discovered, and provided concrete evidence for the existence of the primitive man in the Beijing area and marking a milestone in the history of paleoanthropology.

On February 25, 2007, the Zhoukoudian Site Museum in Beijing exhibited two precious specimens of "bone tubes", which are of equal length and thickness, and have somooth ventral surfaces. Both of which belong to a section of the ribs. The two bone fossils were excavated at the fourth site of Zhoukoudian in 1937, and have been missing since then, and were recently accidentally discovered in the grading of fossil specimens in the museum.
It is inferred that the owner of the bone products is the "Upper Cave Man". This important discovery provides a new idea for further searching for the radius of activity of the "Upper Cave Man".

On July 17, 2015, a press conference was held at the Zhoukoudian Site to announce the results of the excavation of the fourth floor of the first site from 2011 to 2014. In the process of cleaning and excavation in recent years, excavations have been carried out on the upper and lower parts of the fourth layer of accumulation, and a total of tens of thousands of identifiable specimens have been excavated.
