The Great Wall of China is the oldest existing fortress and is listed as World Heritage by the UNESCO. The original length of the Great Wall was about 6,300 km! But the length of Great Wall, which is fixed, has increased by more than three times during the past four years. The length of Great Wall that China has recently announced is 21,191km! The Great Wall is not a rubber band, but how can the length extend so much? The extension of the length of the Great Wall is a trick to emphasize that various ethic groups in Chinese territory are a single historical unit. It is also a trick to argue that Koguryo and Balhae, which are Korean historical countries, belong to their territory. China doesn't hesitate to distort history for their own interests... Does China give up becoming a global leader country as G2 nation and decide to become criticized hegemony?
