Only gets 5 hits on Google. When Google translates them into English, you get really weird stuff (assuming decayed vegetables and lawn clippings are not actually used in Oriental cooking).
It mentions this suace only in the context of cooking soybeans (which I can't eat due to some sort of food sensistivity) and chicken feet (which I haven't quite got up the courage to try).
I bought a bottle of it because the packaging was so beautiful and the ingredients list so incredibly uninformative: water, less, spice, salt. I wonder what "less" was intended to mean. Also, for only $1.99 it was well worth the money to satisfy my curiosity.
Note: The page is japanese, even though it does talk about shanghai cooking. Unfortunately, my japanese is not quite good enough to give you the recipes :-).
