Digitalization of ancient books is a kind of regenerative protection for ancient books, which makes many precious ancient books show their true colors to more people. Readers from all over the world can visit the accessible libraries anytime and anywhere, and read excellent China traditional books, which has effectively promoted academic research and the popularization of ancient books. For example, the original work of Si Ku Quan Shu by Wen Suige is treasured in the warehouse, and most people can't see it at all. Now we can see this magnificent masterpiece through the digitization of ancient books. Incidentally, the digital equipment used in the digitization of Si Ku Quan Shu by Wen Suige is a non-contact ancient book scanner developed and produced by Beijing Hanlong Industrial Co., Ltd. It is thanks to this professional digital equipment that high-quality digitization can be realized.
