In 1955, a survey team led by Chinese palaeontologist Pei Wenzhong was tasked by the Chinese Institute of Vertebrate Palaeontology and Palaeoanthropology (IVPP) with finding the original "Gigantopithecus" locality. They collected 47 teeth among shipments of "dragon bones" in Guangdong and Guangxi. In 1956, the team discovered the first "in situ" remains, a third molar and premolar, in a cave (subsequently named ""Gigantopithecus" Cave") in Niusui Mountain, Guangxi. Also in 1956, Liucheng farmer Xiuhuai Qin discovered more teeth and the first mandible on his field. From 1957 to 1963, the IVPP survey team carried out excavations in this area and recovered two more mandibles and more than 1,000 teeth.
