The Han Dynasty and the Han Dynasty add up to 420 years, that is, 2 14 years in the Western Han Dynasty and 0/96 years in the Eastern Han Dynasty. During the Han Dynasty, there was a brief new dynasty (9- 23 AD) in which Wang Mang usurped the Han Dynasty and stood on his own feet. The Tang Dynasty was 289 years. The largest territory of the Han Dynasty was140,000, and that of the Tang Dynasty was150,000. During the reign of Emperor Wu of the Han Dynasty, no one else could do it. The Tang Dynasty was a friendly dynasty, and the submission of the four parties was not by force. Of course, it was during the Zhenguan period, during the Kaiyuan period, not after the Anshi Rebellion.

When the Tang Dynasty was strong, its territory was surprisingly large. Compared with China, there are less Heilongjiang, Tibet and Yunnan, and more than half of Central Asia, Mongolia and Lake Obebaikal, which is more than 6,543,805 square kilometers. After decades, it was reduced to 6.5438+0.03 million square kilometers, and even reduced to 8 million square kilometers after the Anshi Rebellion, which is a huge shrinkage in history. Except for the vast territory in the early Tang Dynasty, the territory in the early and middle period was similar to that in the Sui Dynasty, only because Koguryo was destroyed and Northeast China and Korea were added.

Han (140,000) On the basis of the Qin Dynasty, the Han Dynasty annexed Korea in the east and the western regions (Xinjiang) in the west. The south occupied Hainan Island. Occupied all the places around China suitable for human survival. Areas not occupied by the Han Dynasty are not suitable for farming civilization. For example, the virgin forests in Heilongjiang River Basin, Qinghai-Tibet Plateau, Mongolian Plateau, Myanmar, Thailand and Taiwan Province Province. The territory of the Han Dynasty constitutes the basic distribution area of Han people. It was also the biggest expansion period in ancient China. In the heyday of the Han Dynasty, Liang Wudi of the Western Han Dynasty and his descendants, Xuan Di of the Western Han Dynasty, Emperor Guangwu of the Eastern Han Dynasty and Emperor Hanming of the Eastern Han Dynasty laid a magical land. Now almost all of Korea, northern Vietnam. Most of Xinjiang, including a considerable amount of land in Central Asia, is within the scope of the Western Regions of the Han Dynasty, as well as all large areas of Sichuan and Yunnan-Guizhou. All the land in Liaoning was also under the control of the Han Dynasty, and a piece of land in Jilin and Inner Mongolia was also under the control of the Han Dynasty, with an estimated land area of/kloc-0.04 million square kilometers. At the end of the Eastern Han Dynasty, it shrank severely, and the land in Yunnan, Guizhou and Inner Mongolia was lost, as well as the land in northern Xinjiang. The land should be 8.9 million square kilometers.
