Eight wonders of the world refers to the Hanging Garden, the Alexandria Lighthouse, the Colossus of Rhode Island, the statue of Zeus in Olympia, the Temple of Al themis, the Solas Mausoleum, the Egyptian Pyramids and the Terracotta Warriors and Horses in the Mausoleum of the First Qin Emperor in China. In fact, the first seven are the "seven wonders of the world" recognized since ancient times, and the "eighth wonder" is inconclusive in the world. This sentence has been widely circulated since 1978 Chirac's visit to China. Some people think that the Great Wall and the Taj Mahal are the eighth wonder.
