The art of building is one of the greatest treasures of human history. They firstly built to live in, and then gradually developed a variety of purposes----temples, monasteries, towers?and as years pass by, they are no longer just buildings standing there, they are manifestations of local culture; they are art treasures; they are treasures of humanity. If you remove these brilliant titles, traces of history will be explored. Put these architectures to background of your flippingbooks, to create an amazing flippingbook with your own style.
