In the 1980s and 1990s，in order to better realize their own social functions of collection，research，and education in the contemporary era，and obtain greater social benefits，foresighted museums began their digital exploration. The pioneers of museum digitalization in my country，represented by the National Museum of China and the Palace Museum，have practiced and explored in digital protection，digital display，digital communication，and digital integration，which have answered the question of how museums can achieve digitalization. The sudden outbreak of the novel coronavirus pneumonia （COVID-19） changed the original trajectory of everyone’s life. Based on the epidemic situation and the non-contact and non-aggregated epidemic prevention methods，museums around the world have to accelerate the process of digital transformation and use online opening to resolve the impact of offline closures. However，as the digitalization of museums continues to deepen，some structural issues that hinder the digitalization of museums have become increasingly prominent，such as the low degree of professionalization of personnel engaged in digital activities，insufficient budgets for digital activities，and the imbalance of global museum digitalization. More and more cultural institutions are deeply aware of the importance of digitization，set out to solve these problems，and promote the development of museums in a more intelligent direction.
