Here is the gaiwan: the lid repeats the theme of the bowl, but I am posting both in case one has a clue the other doesn't.

I put a mirror there so you can see the other side of the gaiwan. Clicking will reveal a larger image.

Here's the little cup, again with the mirror. Also, of course, clicking will give a larger view. The dragon on the far side seems to have a tongue or snake or spit or fire shooting from its mouth and hitting the little red thing between the two dragons.

Anyone know what the Dual Dragon story is? or what that thing between them is?
