Your mark says "德昌陶瓷". Google translate will mistakenly translate that as "Johnson Ceramics" and/or "German Ceramics" on occasion -- or maybe it isn't a mistake, there might be something special to the word, but more properly you could call it "Dechang Ceramics". What you need to know is, Googling those four Chinese characters will find you similar pieces.
This is a great page for looking up antique or reproduction Chinese pottery. I use it a lot when answering these questions. However this piece, being more modern, I don't believe is on that page (I didn't see it anyway). In these cases I always have to translate the characters.
