How to divide Shandong Lunan and Shandong Zhongnan?

Thank you for trusting me and inviting me to answer! In order to analyze this topic in depth, we will first explain Lunan and Zhongnan separately.

(1) Lunan, as the name implies, refers to the south of Shandong Province. Suppose you draw a horizontal line in the middle of the map of Shandong Province below, and you can find the answer from the geographical identification method of upper north and lower south.

(2) Southern Shandong usually includes southeastern Shandong, southwestern Shandong and south-central Shandong. These nouns are used to set off a city to a great extent. From the map, southern Shandong should include Heze, Jining, Zaozhuang, Linyi and Rizhao. If Taian is counted as south-central Shandong, then the whole southern Shandong region includes six cities.

(3) According to the commonly used methods of debate

There is no juxtaposition between east and west on the geographical issue of dividing north and south. Otherwise, it is directly divided into eastern Shandong and western Shandong.

④ Combined with the traditional conclusion of "all directions", it can be divided into four directions: east, west, north and south, with northeast, southeast, northwest and southwest as auxiliary directions. The so-called new geographical terms, such as Luzhong, Lunan or Luzhong and Lubei, are all named for locating cities.

Strictly speaking, the division of southern Shandong will be irregular, and it is impossible to determine the north-south boundary with the middle line, because some areas will be half in the south and half in the north.

⑥ According to the data of the national north-south boundary, Henan Province belongs to the northern region, but Xinyang City under its jurisdiction is located in the south. Therefore, this paper analyzes the relative standards for dividing the north and south of the central line.

Shandong Lunan and Lunan both contain the word "nan", but the concepts of these two nouns are completely different. Lunan is an administrative division of Shandong in history, and Lunan area refers to the geographical position of this area.

Let's talk about central and southern Shandong. Central and South Shandong was an administrative region specially divided by the state according to the needs of the situation at that time in the late 1940s. At that time, the central and southern Shandong administrative region was divided into many special areas, including Jining, Tai 'an, Linyi, Zaozhuang, Rizhao and Xuzhou.

At that time, Xuzhou was still under the jurisdiction of Shandong Province, but the Central South Shandong Administrative Region only existed for two years, which was revoked according to the situation because of the establishment of New China.

At present, Lunan area refers to the noun of an azimuth area. Literally, it means southern Shandong, mainly including Linyi, Zaozhuang, Heze, Jining and Rizhao. The population of this area accounts for 1/3 of Shandong Province.

The nationalities in this area basically belong to the Central Plains, and most dialects belong to the Central Plains Mandarin. Living and eating habits are very similar to those in northern Anhui, northern Jiangsu and eastern Henan.

However, the southern Shandong area is divided into two concepts on many occasions. One is pure southern Shandong, which mainly refers to Zaozhuang and Linyi. In addition to pure southern Shandong, southwestern Shandong is the most frequently used area at present. Basically, whether it is weather forecast or economic division, it is called southwest Shandong.

Southwest Shandong mainly includes Jining and Heze. Rizhao, the only remaining city in southern Shandong, strictly belongs to southeastern Shandong, but according to the map shape of Shandong, the name of southeastern Shandong is rarely used.
