The narrative design of historical-themed exhibitions should be built upon clear thematic narratives and comprehensive narrative structures.Departing from the conventional chronological narrative logic,the exhibition entitled"Unity under the Heaven:The Qin and Han Civilizations Theme Exhibition"adopts innovatively a parallel narrative framework and a multi-threaded narrative approach,based on a thorough interpretation of the material culture of the Qin and Han civilizations.Enhanced with original multimedia installations and interactive touchscreens,the exhibition provides audiences with a three-dimensional presentation of the outstanding achievements of the Qin and Han civilizations and their significant contributions to world civilizations.
