Tsinghua bamboo slips were first smuggled into Hong Kong from an ancient tomb in China during the Warring States period, and appeared in Hong Kong in 2006. Because academic institutions could not buy stolen cultural relics, Tsinghua had to entrust alumni to rescue them from Hong Kong by donation. It was taken to Peking University for AMS carbon 14 dating, and the year of tree ring correction was 305 years BC, that is, the middle and late Warring States period. As an academic institution, Tsinghua can't be traced back to Hubei, because it was smuggled into Hong Kong through illegal channels and changed hands many times. In order to protect the sales channels, it refused to disclose the "rules" of cultural relics dealers. On June 5438+ 10, 2008, an appraisal meeting was held. The 1 1 experts who participated in the appraisal are basically famous scholars in the field of archaeological historical documents and ancient Chinese characters from other units (the appraisal team leader is Li and Qiu Xigui). Now the suspicion is false, and none of them are engaged in ancient Chinese characters. Up to now, four editions of Tsinghua bamboo slips have been compiled and will continue to be published at the rate of one edition per year. Researchers can carefully study the characters and simplified characters of these bamboo slips through high-definition photos, and they can't afford books. There is an electronic version online. 1. Tsinghua bamboo slips are saturated bamboo slips with water content close to 400%. They are as soft and fragile as boiled noodles, which is beyond the reach of modern technology. And there are more than 2,000 pieces. The method of passing the carbon 14 test is written on the bamboo slips without characters in the Warring States period, but it is impossible to find so many water-filled bamboo slips without characters in the Warring States period (it is possible to make wooden slips, and there have been cases where ancient tombs were used to make fake slips). Even if you can find bamboo slips, you should have suitable ink so as not to fall down and be soaked. Mr. Hu Pingsheng, former director of China Institute of Cultural Relics, introduced that he had personally done experiments with colleagues who protected bamboo slips. It is extremely difficult to write with Gu Mo in Ming and Qing Dynasties on ancient bamboo slips, and it is impossible to integrate them with bamboo slips. Even if the ink can be developed, these bamboo slips have another feature. When cleaning in Tibet, they were found to have a hard shell formed by a layer of clay board (see the picture below). As Mr. Li Junming, a researcher at Tsinghua University Unearthed Literature Research and Protection Center, said: "Who can fake the soil thousands of years ago?" Below: The state of bamboo slips in hiding. Bamboo slips are set off and supported by bamboo pieces inside, covered with multi-layer plastic films to prevent water loss, fixed at both ends with adhesive tapes, and then put into a plastic tube half a meter long.
