Human activity existed in Liaocheng City as early as 6,000 years ago. With over 2,500 years of history, it is a city where the Yellow River and the Grand Canal meet, a place where different cultural forms, including Yellow River culture, Grand Canal culture, and agricultural culture, have interacted and blended. During the Warring States period, Liaocheng was a city in the western part of the State of Qi. Under the Qin Dynasty's prefecture-county system, its territory belonged to the Eastern Prefecture. In August 1997, Liaocheng Prefecture and the county-level city of Liaocheng were abolished, and the prefecture-level city of Liaocheng was established. Located between the Shandong Peninsula urban agglomeration and the Central Plains urban agglomeration, Liaocheng is included in major national and provincial strategies such as the coordinated development of the Beijing-Tianjin-Hebei region, the Central Plains Economic Zone, and the ecological protection and high-quality development of the Yellow River Basin. Liaocheng is an important supply base for high-quality grains, vegetables, fungi, meat, eggs, and dairy products in China, and is home to leading enterprises in these industries such as Xinfa Aluminum & Electricity, Dong-E-E-Jiao, and Luxi Chemical.
