The city of Yongji, located in Shanxi Province, possesses a rich and multi-century history rooted in deep antiquity. The modern city is the successor to the ancient administrative and cultural center known as Puzhou, which played a key role in Chinese history across many dynasties. The first settlements in this area appeared thousands of years ago, and during the Han Dynasty (206 BC – 220 AD), the area was known as Puban.
The city reached its peak, already under the name Puzhou, during the Tang Dynasty (618–907 AD), becoming an important political, military, and cultural center. The city's growth and significance were fueled by its strategic position. Located on the east bank of the Yellow River, Puzhou controlled one of the most vital crossings connecting the capital Chang'an (modern-day Xi'an) with the eastern regions of the country, making it a key transport and military hub.
The city's economic power and engineering fame were bolstered by the famous Pujin Floating Bridge, built in the 8th century. This structure, a marvel of its time, facilitated active trade and the movement of troops. For centuries, Puzhou also served as a prefectural center, holding significant administrative influence in the region.
Puzhou was not only a fortress and trade center but also a place of cultural attraction. It was home to the famous Stork Tower, first erected during the Northern and Southern Dynasties period (420-589 AD). It became known throughout China thanks to a poem by Tang Dynasty poet Wang Zhihuan, turning into a symbol of the quest for new heights and knowledge. The city's economy was closely tied to its position on the Yellow River, which promoted the development of agriculture and river trade.
