Dareu Mahjong C

Google Translate and 2 friends who speak Chinese don't agree on most of these names, so I'm just assigning them arbitrary letters.  Dareu Mahjong switches are a really cool idea that I don't fully understand. Half of these aren't real symbols used in Mahjong as far as I can tell. They also don't come randomly, but with a set variety in the packs with one of them (arbitrarily J in my name scheme) having only one per 35 pack.  With a POK top, nylon bottom, and POM stem, these sound pretty nice.
