60th Anniversary Of Communist Party, Beijing, China

Top-level political divisions of China have altered as administrations changed. Top levels included circuits and provinces. Under that, there have been prefectures, subprefectures, departments, commanderies, districts, and counties. Recent divisions also include prefecture-level cities, county-level cities, towns and townships.
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.
