Now there are 16 prefecture-level units in Shandong on the map, but in the early Qing Dynasty, there were only six states in Shandong, which were inherited by the Ming Dynasty.

Six states were established in the Ming Dynasty, and Jinan Prefecture was the capital of Shandong Province at that time, including Jinan, Tai 'an, Binzhou and Dongying.

Yanzhou Prefecture has a large area, covering Jining, Cao Zhou, Dongping and 23 surrounding counties.

Qingzhou Prefecture has an area similar to that of the first two states, but there are few administrative units, only one state, 13 county. On the other hand, Qingzhou Prefecture is Dongchang Prefecture, with a small area but many administrative units, including Gaotang Prefecture, Zhou Pu Prefecture, Linqing Prefecture and 15 County.

Laizhou area is not famous. It has a city that we all know now-Qingdao. At that time, Qingdao was just a fishing village

The smallest government in Shandong is Dengzhou, including Ninghai Prefecture, and there are 17 counties around it, including Yantai and Weihai.

During the war in the early Qing Dynasty and the late Ming Dynasty, the society was very chaotic and the population in the society was much less, so only six counties were set up. At the beginning, six counties were set up for the convenience of management, but after the development of Kangxi era, the population increased a lot. When Yongzheng ascended the throne, the previous six counties were obviously too difficult to manage, so Yongzheng set up many Zhili States in Shandong, but with the passage of time, many Zhili States gradually became counties.

At first, Tai 'an Prefecture belonged to Jinan Prefecture, which was divided into five counties. Later, after Wuding Prefecture was promoted to Zhili Prefecture, it was divided into three counties of Jinan Prefecture. Wuding Zhili Prefecture and Tai 'an Zhili Prefecture were promoted to the state at the same time, which is the predecessor of Binzhou City and a part of Dongying City.

With the repeated slimming of Jinan prefecture, there are only a dozen counties left. Yanzhou mansion was too big at that time, and it was divided into many places. To the east is Jining House, which was later promoted to Zhili House, but the area is very small, only three counties, but the terrain of Jining House is now Jining City, and the former Yanzhou House has now become Yanzhou District of Jining City.

At that time, the court wanted to keep Yanzhou Prefecture, but its eastern area was too large. Yizhou County originally belonged to Yanzhou Prefecture, and was later upgraded to Yanzhou Prefecture. Yizhou Prefecture is divided into two counties of Yanzhou Prefecture, and the area is still very small.

The regional division in Yongzheng period basically stabilized the terrain of Shandong. Later, after Qianlong succeeded to the throne, Linqing House was promoted to Zhili House.

Later, after the Republic of China, due to the change of the situation at that time, the geographical division of Shandong was very complicated, but later the topographic division of Shandong was based on the division of Qianlong at that time.
