History 
Yanzhou was the first place to install the "school-fields" xuetian in 1022, during the Song dynasty.

In early European sources, based on accounts by French missionaries, the name of Yanzhou (Fu) is transcribed in the contemporary French manner, as Yen-tcheou-fou; however, when reading 18th- and 19th-century books in French or English, care should be taken not to confuse Yanzhou in Shandong with the identically transcribed Yanzhou in Zhejiang.

Geology 
The land structure of the Yinzhou area belongs to the Luxi fault block uplift (level III) and the Zhangzhou fault (Grade IV) unit. The eastern part of the boundary is the Yishan fault, the west is the Sunshidian fault, and the north is the Wensi fault. It is the Fushan fault. Yanzhou is part of it. The basement is the metamorphic rock series of the Mount Tai Group. The Paleozoic, Mesozoic and Cenozoic strata are developed above the basement. Among them, rich industrial coal seams are formed in the Late Paleozoic strata, which is an important base for Yanzhou becoming national coal resources. The tectonic movement in the territory has shaped various structural topography, which are roughly two types of fault structure and fold structure. The strata of all walks of life are developed from the old to the new for the Early Paleozoic strata, the Paleozoic strata, the Mesozoic strata, and the Neogene stratigraphic strata. In the early Paleozoic, the horizon was in a state of slow decline, with large-scale transgression, and the deposition of thick shallow sand shale and carbonate rock formations. The Ordovician rocks in the Paleozoic are mainly light gray and gray thick layered limestone, crystalline limestone and leopard skin limestone; the Carboniferous rocks are mainly gray-white siltstone, clay rock, shale and thin layer limestone. Several layers of coal; the two rocks are mainly grayish white, dark gray sandstone and variegated mudstone and brown shale, rich in plant fossils. The Mesozoic Jurassic rocks are mainly brown sandstone, conglomerate, variegated mudstone and glutenite. The Cenozoic is made up of Tertiary and Quaternary strata. The Tertiary is sandstone, sticky sandstone, and mudstone; the Quaternary strata are loose rock formations composed of Wenyu alluvial deposits. The west is the Wenhe alluvial fan, the east is the Weihe alluvial fan, and the two overlapping alluvial fans are located in the area of Qianqian-Da'an-Tianqi Temple.

Yanzhou District is located in the sloping plain of the southwestern part of the Mount Tai in the Luzhong Mountains. The west is flooded by the flood waters, and the flood alluvial landforms are obvious; the eastern waters are discharged to the southwest, and the terrain is inclined from the northeast to the southwest; the central Guangfu River and the Yangjiahe River are parallel and the terrain is low. The ground elevation is 60~38 meters, the height difference is 22 meters and the average elevation is 49 meters, and the average slope is 1/1500. The northeast is affected by the structure and is a shallow buried area of the Tertiary, with a large slope on the ground. The plain area is 64,670 hectares, accounting for 99.7% of the total area; it is divided into three types: micro-sloping ground, depression and slow-moving. The area is 45,601 hectares, accounting for 70.35% of the total area; the area is 12276.9 hectares, accounting for 18.94% of the total area; the area is 6792.2 hectares, accounting for 10.48% of the total area.

The hills in the territory belong to the bedrock of the Mount Tai hidden under the Quaternary cover. There is a hill 15 kilometers west of the city, named Ziyang Mountain. It is the only hill in Yanzhou. It is a bare hill of the Ordovician limestone. It is a low hill type. It is divided into two peaks, east peak is 75 meters above sea level, and west peak is 72.5 meters above sea level. The mountain is spread from east to west, 1.5 kilometers long and one kilometer wide, covering an area of 1.5 square kilometers. The rock is limestone, and the Qing Dynasty has been sporadic mining, although it is forbidden. In the later period of the "Cultural Revolution", the trees on the mountain were cut down, and the mountain quarry was cut off. The East Peak had become a deep valley, and the west peak still existed.

Climate 
Yanzhou has a monsoon-influenced, four-season humid continental climate (Köppen Dwa). Winters are cold and dry while summers are hot and humid. Monthly daily average temperatures range from  in January to , while the annual mean temperature is . More than 70% of the annual precipitation occurs from June to September, with barely any occurring in the winter months. The city receives 2,461 hours of bright sunshine annually.
