60th Anniversary Of Communist Party, Beijing, China

Most Chinese dynasties were based in the historical heartlands of China, known as China proper. Various dynasties also expanded into peripheral territories like Inner Mongolia, Manchuria, Xinjiang, and Tibet. The Manchu-established Qing Dynasty and its successors, the ROC and the PRC, incorporated these territories into the Chinese empire.
• Geography and climate
China ranges from mostly plateaus and mountains in the west to lower lands in the east. Principal rivers flow from west to east, including the Yangtze (central), the Huang He (Yellow river, north-central), and the Amur (northeast), and sometimes toward the south (including the Pearl River, Mekong (river), and Brahmaputra), with most Chinese rivers emptying into the Pacific Ocean.
In the east, along the shores of the Yellow Sea and the East China Sea there are extensive and densely populated alluvial plains. On the edges of the Inner Mongolian plateau in the north, grasslands can be seen. Southern China is dominated by hills and low mountain ranges. In the central-east are the deltas of China's two major rivers, the Huang He and Yangtze River. Most of China's arable lands lie along these rivers, and they were the centers of China's major ancient civilizations. Other major rivers include the Pearl River, Mekong, Brahmaputra and Amur. Yunnan Province is considered a part of the Greater Mekong Subregion, which also includes Myanmar, Laos, Thailand, Cambodia, and Vietnam.
