Sorry if it seems cryptic, it's not meant to be. Putonghua is the worlds most widely spoken Language, known here as Mandarin or Chinese. The reason I wrote Putonghua was, believe it or not, an attempt to not confuse. I was hoping that a speaker would see it and post a reply.
I have my own boring reasons to strike up a chat with someone in the group who might speak it. There you go nuff said.
