was the basic mode of the Mumun economy, but specialized craft production and a big-man-style redistributive prestige economy emerged in the Middle Mumun. Archaeological evidence has documented cases in which it appears that surplus production of crops, stone tools, and pottery occurred in the Middle Mumun. Artifacts that illustrate regional redistributive systems and exchange include greenstone ornaments, bronze objects, and some kinds of red-burnished pottery. Mortuary practices Megalithic burials, stone-cist burials, and jar burials are found. Some burials in the latter part of the Middle Mumun are especially large and required a significant amount of labour to construct. A small number of Middle Mumun burials contain prestige/ceremonial artifacts such as bronze, greenstone, groundstone daggers, and red-burnished ware.
