無形文化遺産
"Intangible cultural heritage" consists of non-physical aspects of a particular culture, more often maintained by social customs during a specific period in history. The concept includes the ways and means of behavior in a society, and the often formal rules for operating in a particular cultural climate. These include social values and traditions, customs and practices, aesthetic and spiritual beliefs, artistic expression, language and other aspects of human activity. The significance of physical artifacts can be interpreted as an act against the backdrop of socioeconomic, political, ethnic, religious and philosophical values of a particular group of people. Naturally, intangible cultural heritage is more difficult to preserve than physical objects.
