Historic sites witnessed the life and communication of people in olden times. We are able to understand the way of life of the ancients through historic sites. However, facing the passage of time, to preserve the sites or not becomes a difficult challenge and argument. Sometimes the effort of conserving sites is not as fast as the ruin of the natural and human force, natural calamities like earthquakes, typhoons, or artificial factors such as fire accidents and the realistic interests, various issues keep challenging the wisdom of the workers of historic sites. The existing historic sites are legacies of human culture; they offer opportunities for later generations to experience and picture life custom and interpersonal interactions of the former days of the ancients. The value of historic sites is priceless and invaluable.
