The large-scale loss of China cultural relics overseas began in modern times. During the hundred years from the Opium War to the founding of New China, the loss of cultural relics in China reached its peak. Beijing, which collected the essence of China's cultural relics, was savagely plundered by British and French allied forces and Eight-Nation Alliance. In these two catastrophes, Beijing's "savings since the Yuan and Ming Dynasties, from laws and regulations to national treasures, all went up in smoke". Many foreigners plunder under the banner of "cultural inspection". From 1876 to 1928, 42 expeditions arrived in the northwest of China. At present, there are only 20,000 Dunhuang suicide notes in China, while there are 13700 in British Library, 6,000 in French National Library and 65,438 in Russian Studies on Asian Nationalities. Oracle Bone Inscriptions has also lost a lot of overseas. According to incomplete statistics, 200,000 pieces of Oracle bones were unearthed in Xiaotun, Anyang, and 26,700 pieces have been lost overseas, covering Japan, the United States, Britain, Germany, Sweden, Switzerland, France, Russia, Belgium and other countries 12, including Japan12,000 pieces. During the period of War of Resistance against Japanese Aggression, the Japanese invaders openly transported a large number of cultural relics collected in the occupied areas of China to Japan, and also conducted long-term illegal and planned "archaeological" investigations and excavations in Northeast China and North China, and all the exquisite cultural relics unearthed were transported to Japan. After the mid-1980s, driven by high profits, criminals at home and abroad colluded with each other and set off a frenzy of stealing and smuggling precious cultural relics. The cultural relics lost overseas in China are mainly distributed in Europe, America and Japan. In the United States, China's cultural relics are collected in seven centers, such as the Boston Museum of Fine Arts and the Metropolitan Museum of Art, and China's cultural relics are extremely rich, with paintings, bronzes and local chronicles as the bulk. Among them, the collection of China local chronicles is even more amazing. There are more than 4,000 kinds of local chronicles of China provinces, prefectures and counties in the Library of Congress alone. China's cultural relics are mainly collected in Britain, France, Russia, Germany, Switzerland and Sweden. At present, there are as many as 23,000 China cultural relics in the British Museum, of which about 2,000 are on display for a long time. The collection of China cultural relics in the museum covers the whole art category of China and spans the whole history of China. Representative cultural relics include the jade carving slave dragon in the Han Dynasty, the Women's History Map in Gu Kaizhi, Jin Dynasty, the pottery falcon statue in the Southern and Northern Dynasties, the topaz sitting on a dog in the Tang Dynasty, Dunhuang silk paintings and documents. There are more than 0/000 public and private museums in China/KLOC, almost all of which have hundreds of thousands of Japanese cultural relics. Among them, the Tokyo National Museum has the richest collection, including the Oriental Pavilion and five showrooms, which are dedicated to displaying and exhibiting China's ancient cultural relics.
