For the protection of film culture, museums, archives, libraries, audiovisual materials and private collections all share some of the protection functions. It seems that everyone is fighting to protect the cultural heritage of films, but it actually reflects the fragmentation of protection. Each institution protects a little, there is a lack of communication and exchange between institutions, and a lack of unified management based on the protection dimension. This fragmented protection is very inefficient, because the lack of communication will inevitably lead to the uncertainty of the family of the object of protection, resulting in some The protected objects are in an unprotected state. The dispersion of protected objects greatly increases the difficulty of the reasonable use of the heritage, and the meaning and value of protection will be greatly reduced. The text is intended to explain:. ['Decentralization of protection subjects makes film protection difficult.', 'Communication is the solution to the fragmentation of film culture protection.', 'Without a unified protection system, film cultural heritage is difficult to inherit.', 'Fragmentation of labor management is not conducive to the protection of film cultural heritage.']
