As summer approaches, the topic of why it is difficult to "open" the doors of universities has once again attracted attention. One voice is that opening up university campuses to society can maximize their unique role, and the bigger the opening, the better. Some people also express concerns about campus openness, such as concerns about disrupting teaching and research order, adding extra workload, increasing cost expenditures, raising transportation and security risks, and being easily exploited by commercial institutions for profit. In response to this, the official website of the Ministry of Education has clearly stated in the reply to the proposal of the Chinese People's Political Consultative Conference that better opening up university campuses to the public has a positive significance, which is conducive to universities better integrating into society and serving society. In recent years, many universities have gradually opened up to the society, such as increasing more reservation quotas during the peak tourist season, launching fixed campus tourism routes, and organizing volunteers to provide guidance and explanation services. However, why does the topic of university openness always spark debate? The key lies in the "sense of gap" - there is a gap between the openness of the campus and the expectations of the public regarding the relevant management procedures set during the process of opening up to the outside world. Once upon a time, the doors of universities were generally open, and alumni returning to campus, citizens exercising, parent-child outings, and academic exchanges became the norm on campus. During the epidemic, universities strictly implemented entry control measures. However, in today's world where the economy and society have returned to normal, many schools are still "hesitant" and their campus doors are "open and closed" - some adopt online appointment "restricted opening", but either the quota is too small or the appointment process is cumbersome and laggy. Not only do they need to fill in identity information, but they also need facial recognition, turning the convenient process into a "customs clearance test"; Some are like "squeezing toothpaste", without a reservation platform, and are only allowed to enter the school on weekends by swiping their ID card; Some simply continue to adopt a full-time lockdown, making it impossible for the public to find a way to enter the school. Some netizens admitted that in order to enter school, one still needs to have connections or spend money to find "scalpers". This practice of avoiding management difficulties and maintaining "campus calmness" is a manifestation of some universities' backward management thinking and insufficient campus governance capabilities. University openness lies in sincerity and implementation. Resolving the "gap in openness" requires university administrators to face the reasonable expectations of the public for returning to campus and experiencing cultural influence, show courage and wisdom, take on social responsibility, abandon closed thinking, and allow universities to return to their rightful place as public spaces.
