China is a country with a very early civilization and a long and rich history. The compass, gunpowder, the art of paper-making and block printing invented by the ancient Chinese have contributed immensely to the progress of mankind. The Great Wall, Grand Canal and other projects built by the Chinese people are regarded as engineering feats in the world. Man has lived for a very long time in what is now China, according to archaeological finds. In many parts of the country, for instance, fossil remains of primitive ape men have been unearthed. Among them are the fossil remains of the Yuanmou Ape Man who lived in Yunnan Province some 1.7 million years ago.
