Wooden stacked bowls in frame with Chinese writing on bottom

This is a set of hand made wooden bowls, all of which are unique and all of which have different Chinese writing on the bottom.  They stand in a wooden stand that is made of the same dark, lighweight wood.  The rack is all hand made too with mortised joints and the rack keeps the plates in place.  One of the veritcal pieces of the rack is hinged and folds out and down so that the plates are accessible.  4 of the plates have cracks from the edge to the inner rim, but not all the way through the whole bowl.  Some of the bowls have what appears to be woven wire on the lower inner edge at the bottom. The Chinese characters on the bottom of each bowl are different and are hand inked onto the bowls.  The rack measures 22" High and is 8" x 8" square.  The plates all measure approximately 7 1/4" in diameter.  When put together, the set is amazingly light, so I am unable to identify the wood used in the making of this set.
