Chinese archeologists found traces of human activities dating back to over one million years ago at the Longgang Temple Ruins in Hanzhong city, China's Northwestern Shaanxi province. This is important evidence proving that Hanjiang River Valley is one of the birthplaces of Chinese ancient civilization.

Since 2013, the archeological expedition has been founded by the Institute of Vertebrate Paleontology and Paleoanthropology of China Academy of Sciences as well as Shaanxi Archaeological Institute. A large amount of historical relics have been found in succession from the Paleolithic Age to the Shang and Zhou Dynasties (11th century BC-256 BC). More than 30,000 stone tools belonging to the Paleolithic Age were some of the most important finds.
