Cabinets of this type were likely to have been filled with books, scrolls, or paintings. To facilitate transport and to protect the traveling case from moisture or insects, the cabinet was raised on a fitted base and fitted with an upright frame and would have been carried at either end of a long carrying pole. Consequently, the stress placed on the frame required a particularly strong construction, reinforced with inlaid hardware. For a discussion of metal fittings on bookcases, see an article by Curtis Evarts, "Uniting Elegance and Utility: Metal Mounts on Chinese Furniture", JCCFS, Summer 1994, pp. 27-47.
A smaller huanghuali medicine cabinet (58 cm.), in the collection of Dr. R. J. C. Hoeppli, is illustrated by G. Ecke, Domestic Chinese Furniture, Rutland and Tokyo, 1962, p. 135, fig. 107, where Ecke illustrates the chest with the doors open revealing numerous drawers.
