history of china
chinese civilization originated in various regional centers along both the Yellow River and the Yangtze River valleys in the Neolithic era, but the Yellow River is said to be the Cradle of Chinese Civilization. The written history of China can be found as early as the Shang Dynasty (c. 1700 – 1046 BC).,although ancient historical texts such as the Records of the Grand Historian (ca. 100 BC) and Bamboo Annals assert the existence of an Xia Dynasty before the Shang. Oracle bones with ancient Chinese writing from the Shang Dynasty have been radiocarbon dated to as early as 1500 BC. The origins of present-day Chinese culture, literature and philosophy developed during the Zhou Dynasty (1045-256 BC).
In China, a vast land spanning many degrees of latitude with complicated terrain, climate varies radically. China has a variety of temperature and rainfall zones, including continental monsoon areas. In winter most areas become cold and dry, in summer hot and rainy.
Five Temperature ZonesTemperatures vary a great deal. Influenced by latitude and monsoon activities, in winter, an isotherm of zero degrees traverses the Huaihe River-Qinling Mountain-southeast Qinghai-Tibet Plateau. Areas north of the isotherm have temperatures below zero degrees and south of it, above zero. Mohe in Heilongjiang can hit an average of 30 degrees centigrade below zero, while the temperature of Sanya in Hainan Province is above 20 degrees. In summer, most of areas are above 20 degrees centigrade despite the high Qinghai-Tibet Plateau and other mountains such as Tianshan. Among these hot places, Turpan Basin in Xinjiang is the center for intense heat at 32 centigrade on average.
