What is a ginger jar and what was it used for?

I have two antique Chinese ginger jars with lids, i bought them because of their beauty, however I'm curious now as to what the original purpose of a ginger jar was. I see they come in all different shapes, and sizes, but often see the main shape as round. Mine happen to be about 9 in in height and seem to large, just to have once housed ginger root.

What were the original ginger jars used for? Perhaps to ferment beer of other drinks, or maybe just to keep ginger. I hope someone can answer me. I have searched all over the net with this question.

only thing my mother used her's for was to keep ginger in!!!
