Dezhou, called Ande in ancient times, is a prefecture-level city in Shandong Province. Located in the alluvial plain in the northwest of Shandong Province, downstream of the Yellow River, it is the northwest gate of Shandong Province, bordering Cangzhou City, Hebei Province in the north, Jinan City and Liaocheng City in the south, Hengshui City, Hebei Province in the west and Binzhou City in the east. Dezhou is an alluvial plain of the Yellow River. In history, there have been two great migrations of the Yellow River, with thousands of crevasses, which created a terrain with high southwest and low northeast. The basic climate is characterized by the obvious influence of monsoon, distinct four seasons and obvious boundaries between cold, heat, dryness and wetness. Administrative area 10356 square kilometers.
During the Xia and Shang Dynasties, Dezhou was a Hou State, and there was a Wei family with a poor family. The Qin dynasty abolished the enfeoffment system and changed it to the county system, and later changed it to the Northern Qi Dynasty. Ande County was established in Han Dynasty, and Guang Chuan, Changhe, Jiangling, Lingzhou, Lingxian and Dexing counties were established in Sui, Tang, Song, Yuan, Ming, Qing and Republic of China. For more than 2,200 years since the Qin Dynasty, Dezhou has changed its jurisdiction six times, in different periods and different regions.
