The Xi'an Museum is composed of a museum with a round sky and a local design, a simple and elegant Jianfu Temple, and a beautiful Small Wild Goose Pagoda. The design of the trinity of museum, garden, and tower is unique in the national museum industry. We should protect and manage the cultural relics that embody the traditional culture of the Chinese nation, while strengthening research and utilization. Let history speak and cultural relics speak. While inheriting the achievements and glory of our ancestors, enhancing national self-esteem and confidence, we should also remember the setbacks and lessons of history, so as to avoid detours and move forward better. "Internet plus", digital technology enables the protection and utilization of cultural relics. "The application of digital technology is a qualitative change in the field of cultural relics protection." Looking at the colorful three-dimensional model of the tomb stone outer coffin of the Shijun of the Northern Zhou Dynasty in the computer, Fu Haixiang, the head of the collection preservation department of the Xi'an Museum, sighed with emotion. The outer coffin of Shi Jun's tomb in the Northern Zhou Dynasty is an extremely important cultural relic in the Xi'an Museum, and the inscriptions and reliefs on it are very precious. The model obtained through high-precision laser scanning is mapped and synthesized with high-resolution texture images of hundreds of millions of pixels, forming the final color 3D model. This application not only facilitates researchers to access data as needed at any time, but also avoids potential harm to cultural relics caused by contact, "said Fu Haixiang. As a national key protection unit of ancient books, the Xi'an Museum has a collection of more than 100000 ancient books. How to make ancient books go out of the Sutra Pavilion, transform them from cultural relics into documents, and unleash their own value has always been a question that Fu Haixiang ponders. Cultural relics should be preserved well, and literature should serve society more because it is essentially a book and cannot be 'locked' in museums, "said Fu Haixiang. The digital protection project of ancient books provides a solution to this problem. With the help of "Internet plus", at present, more than 100000 volumes (pieces) of ancient books collected by Xi'an Museum have achieved the complete description of authors, binding, copyright and other contents. Through the exchange of ancient literature with important ancient book collection units such as the National Library and National Edition Library, ancient books have become "alive".
