In the 20th century, archaeologists made tens of thousands of discoveries in China. In 2001, the
Institute of Archaeology of the Chinese Academy of Social Sciences organized a poll of experts who selected
China's 100 major archaeological discoveries in the 20th century, with
Yinxu receiving the most votes. One of the archaeological discoveries of China is a
Guanyindong Palaeolithic cave site, discovered in 1964 by archaeologist
Pei Wenzhong in
Qianxi County,
Guizhou. During several archaeological excavations in the 1960s and 1970s, most of the material remains were gathered from the cave entrance. About one-third of the artifacts were extracted from the upper layer which is called "Layer 2" or "Group A" by archaeologist Prof. Li Yanxian, and the rest of them were collected from the lower layers- "Layers 4–8" or "Group B". According to Associate Professor Bo Li, besides several non-Levallois flakes, archaeologists examined more than 2000 stone artifacts from Guanyindong and revealed proof of
Levallois concepts on 45 samples (including cores, flakes and tools). It contains the earliest evidence of stone artefacts made using the
Levallois technique in China. In November 2018, the discovery of these stones dated to approximately 170,000-80,000 years ago were announced by the
University of Wollongong. A number of Chinese artifacts dating from the
Tang dynasty and
Song dynasty, some of which had been owned by
Emperor Zhenzong were excavated and then came into the hands of the
Kuomintang Muslim General
Ma Hongkui, who refused to publicize the findings. Among the artifacts were a white marble tablet from the Tang dynasty, gold nails, and bands made out of metal. It was not until after Ma died, that his wife went to Taiwan in 1971 from America to bring the artifacts to
Chiang Kai-shek, who turned them over to the
Taipei National Palace Museum. What were identified as the oldest-known
noodles were found in an earthen bowl at the 4,000-year-old site of
Lajia on the
Yellow River in China. The noodles, discovered by
Ye Maolin of the
Chinese Academy of Social Sciences and analyzed by
Lu Houyuan of the
Chinese Academy of Sciences and colleagues, were 50 cm long and had been made with two strains of millet. ==Future==
