Buna Dimineata (one of the few things I know in romanian besides da, nu and multumesc)
I worked often with romanians (in my current company but also in my education as gardener since a lot of garden helpers came from romania) and so, i know a few things.
Cities: Bucharest (capital), Cluj-Napoca (also known as Klausenburg in germany) and Constanta (city on the black sea)
There are a lot of myths in romania like vampires, ghosts and such things. There is also this forest called Hoja Baciu which is one of the most famous horror forests in europe.
I don't know if it is still there, but they had parts where they spoke german. it was Transylvania, which is also knowns as Siebenbürgen in german. The language was called Siebenbürgen-Sächsisch, but it is actually related to the dialects of my area, the rhineland, and not saxony.
