A report on Han dynasty and Shaanxi

The seventh-largest administrative district by area at 453700 km2, Gansu lies between the Tibetan and Loess plateaus and borders Mongolia (Govi-Altai Province), Inner Mongolia and Ningxia to the north, Xinjiang and Qinghai to the west, Sichuan to the south and Shaanxi to the east.

Gansu is abbreviated as "" (Gān) or "" (Lǒng), and was also known as Longxi or Longyou prior to early Western Han dynasty, in reference to the Long Mountain (the modern day Liupan Mountain's southern section) between eastern Gansu and western Shaanxi.

The Qin dynasty, or Ch'in dynasty in Wade–Giles romanization , was the first dynasty of Imperial China, lasting from 221 to 206 BC. Named for its heartland in Qin state (modern Gansu and Shaanxi), the dynasty was founded by Qin Shi Huang, the First Emperor of Qin.

Despite its short reign, however, the lessons and strategies of the Qin shaped the Han dynasty and became the starting point of the Chinese imperial system that lasted from 221 BC, with interruption, development, and adaptation, until 1912 AD.

Shanxi borders Hebei to the east, Henan to the south, Shaanxi to the west and Inner Mongolia to the north.

The Han Dynasty (206 BC – AD 220) ruled Shanxi as the province of Bingzhou.

Xi'an (, ; ; Chinese: ), frequently spelled as Xian and also known by other names, is the capital of Shaanxi Province.

Known as Chang'an in much of its history, Xi'an is one of the Chinese Four Great Ancient Capitals, having held the position under several of the most important dynasties in Chinese history, including Western Zhou, Western Han, Sui, Northern Zhou and Tang.

The network began with the Han dynasty's expansion into Central Asia around 114 BCE, which largely pacified the once untamed region.

Similar animal-shaped pieces of art and wrestler motifs on belts have been found in Scythian grave sites stretching from the Black Sea region all the way to Warring States era archaeological sites in Inner Mongolia (at Aluchaideng) and Shaanxi (at Keshengzhuang) in China.

Its neighboring provinces are Shaanxi, Shanxi, Hebei, Shandong, Anhui, and Hubei.

The empire quickly collapsed after the death (210 BCE) of Ying Zheng and was replaced by the Han dynasty in 206 BC, with its capital at Chang'an.

Sichuan neighbors the Qinghai to the northwest, Gansu to the north, Shaanxi to the northeast, Chongqing to the east, Guizhou to the southeast, Yunnan to the south, and the Tibet Autonomous Region to the west.

Following the declining central government of the Han dynasty in the second century, the Sichuan basin, surrounded by mountains and easily defensible, became a popular place for upstart generals to found kingdoms that challenged the authority of Yangtze Valley emperors over China.

The Qin was followed by the more stable Han dynasty (206 BCE – 220 CE), which established a model for nearly two millennia in which the Chinese empire was one of the world's foremost economic powers.

The Jiangxi Soviet was wiped out by the KMT armies in 1934 and was relocated to Yan'an in Shaanxi where the Long March concluded in 1935.

During the Western Han dynasty, Emperor Wu sent the general Wei Qing to reconquer the Hetao region from the Xiongnu in 127 BC. After the conquest, Emperor Wu continued the policy of building settlements in Hetao to defend against the Xiong-Nu.

It borders eight provincial-level divisions in all three of the aforementioned regions (Heilongjiang, Jilin, Liaoning, Hebei, Shanxi, Shaanxi, Ningxia, and Gansu), tying with Shaanxi for the greatest number of bordering provincial-level divisions.

Hanzhong (abbreviation: Han) is a prefecture-level city in the southwest of Shaanxi province, China, bordering the provinces of Sichuan to the south and Gansu to the west.

The founder of the Han dynasty, Liu Bang, was once enfeoffed as the king of the Hanzhong region after overthrowing the Qin dynasty.
