It lies southeast of Frankfurt am Main in the Frankfurt Rhine Main Region and has the greatest population of any municipality in the Offenbach district.  It came into being in 1979 when the greater community of Rodgau was raised to town, after having been formed through a merger of five formerly self-administering communities in the framework of municipal reform in Hesse in 1977.  The current constituent communities’ history reaches back to the 8th century. Yulin () is a prefecture-level city in the Shanbei region of Shaanxi province, China, bordering Inner Mongolia to the north, Shanxi to the east, and Ningxia to the west.

He was born in what is now Tongchuan, Shaanxi on September 6, 1878.  His whole life was spent in the army, and ruled Shaanxi from the city of Yulin for 23 years.  He was called "榆林王" or "the Yulin king" because of his major base at Yulin, though he was much more powerful and actually controlled most of Shaanxi for most of his reign.  He died of an accidental self-inflicted gunshot wound February 1, 1936. The forest dormouse ("Dryomys nitedula") is a species of rodent in the family Gliridae found in eastern Europe, the Balkans and parts of western Central Asia.  It is categorized as being of least concern in the "IUCN List of Threatened Species" due to its wide range and stable population trend.  Forest dormice have a diploid count (2n) of 48 chromosomes.  Even though this species lives in a variety of geographic locations, its greatest population density is in the forests of central Moldova, in Transcaucasia, in the mountains of Central Asia.  In most other locations, population density of this species is rather low.  Population density is dependent on many factors.  But the main features that this species depends on for choosing a location are the presence of the appropriate food sources as well as good foliage that can be used for a habitat.  The reason why the forests in central Moldova have the highest population density is they provide the largest diversity of food sources which are available throughout the year.  This location also provides the best type of foliage for the forest dormice to build their nests as well as swing from branches.  The combination of both of these aspects allows for this species to have its highest needs met.  Therefore, during mating season they produce offspring who also stay in the same general area when they mature.  It makes sense not to move from an area if it is providing for your most basic needs. Tongxiang City () (IATA: TVX) is a county-level city, part of Jiaxing, in northern Zhejiang Province, China.
