The city of Huaian, located in the modern Jiangsu province of China, boasts a rich and centuries-old history spanning over 2,200 years. The first settlements in this territory appeared approximately 5,000 to 6,000 years ago and belong to the Qingliangang culture. Officially, Huaian was established as a county during the Qin Dynasty (221–206 BC). However, a pivotal moment in the region's early history occurred even earlier, in 486 BC, when the Hangou Canal was dug by order of the King of Wu, connecting the Huaihe and Yangtze rivers. This hydraulic engineering feat became one of the first sections of the future Grand Canal of China and laid the foundation for the city's future prosperity.
The key factors in Huaian's formation are inextricably linked to its unique geographical position. Its location at the intersection of the Grand Canal and the Huaihe River turned the city into a strategically important transport and trade hub. For many centuries, especially during the Ming and Qing dynasties, Huaian was one of the four largest urban centres along the Grand Canal, alongside Suzhou, Hangzhou, and Yangzhou. Vital supplies of grain, salt, and other goods from the fertile south to the northern capitals passed through here. This status ensured not only economic prosperity for the city but also significant political influence. After the founding of the Ming Dynasty, the Huaian Prefecture was established here, controlling vast territories north of the Yangtze.
The city's early cultural and economic features were shaped by its metropolitan status and flourishing trade. Huaian, together with Yangzhou, is considered the birthplace of Huaiyang cuisine—one of the eight great culinary traditions of China, renowned for its emphasis on freshness and the natural flavour of ingredients. The city's economy was centred around the management of waterways, tax collection, and cargo transportation along the Grand Canal. Administrative institutions controlling shipping, as well as large warehouses and granaries, were located here. Its rich historical heritage and strategic role in the life of the empire made Huaian an important cultural centre, confirmed by its inclusion in the list of National Famous Historical and Cultural Cities of China.
