county in Shandong province
鄩 is a rare kanji used primarily as a proper noun for a county in Shandong province. Its standalone meaning is limited to this geographical reference.
鄩 combines 尋 (which may contribute a phonetic element) with the right-side ⻏ (village/city radical), suggesting a place name. The exact historical development is uncertain.
The left side 尋 suggests searching, and the right side ⻏ is a city wall. Imagine searching for a specific county in Shandong on an old map marked by a walled city.
For シン, picture the county's name written in shiny ink on the map: shiny -> シン, and you find the Shandong county.
