Non-material culture is difficult to preserve because it includes a society's intangible and abstract components.

Non-material culture consists of elements such as beliefs, values, customs, language, and art. These are intangible and abstract components that exist in people's minds and are not physical objects. Since they are not physical, it is difficult to preserve them in the same way as material culture, which includes physical artifacts and objects. Non-material culture is passed down through socialization and communication, which can be influenced by changes in technology, social norms, and other factors that can lead to changes or loss of cultural traditions. As a result, it can be challenging to preserve non-material culture over time.
