Lots of problems regarding cultural heritage conservations come from the controversial issues of authenticity and the mechanical ideology. We must regard cultural heritages as living bodies with the life authenticity which contains the interaction of the people, the cultural heritage, the natural environment, and the social environment. Since the dynamic characteristics of the development of cultural heritages, we had better consider whether cultural heritage conservation projects meet the authenticity criteria of “keeping the same” type, “modern interpretation” type, or “future translation” type.
