Machu Picchu

Hundreds of years ago, the Inca Empire humiliatingly became a colony of Spain. The residents living on this ancient land had no resistance to the infectious diseases brought by the Spaniards. As a result, the population was sharply reduced by ninety percent within a short period. In such a nation without written words and only oral transmission to record history, the demise of people means the end of history. Fortunately, the Incas who were proficient in stone construction left behind the ruins of the ancient city of Machu Picchu, which cannot speak but will last forever. Even if there are no more Incas in this world, the traces of the Inca Civilization on earth will be indelible.
