Collection introduction: After decades of development, Nanjing Museum has a collection of 419,000 pieces and is one of the three major museums in China. Among the rich exhibits, the largest number of original Qing palace porcelains, the cultural relics unearthed from the Yin Ruins have the highest scientific value, and the ethnic cultural relics of the Yi, Naxi, Dai, Tibetan and Lisu people in the southwest are the most distinctive. What the academic circles at home and abroad pay the most attention to are the various cultural relics obtained by the museum's Archaeological Institute personally hosting or participating in surveys and excavations.
