Dougong is the system of interlocking wooden brackets set atop a column to catch the weight of the roof beams above and step it inward and downward through a stack of mortise-and-tenon joints, cut with no nails or glue, until it lands on the column head. A block (dou) seats on the column and carries an arm (gong), which in turn carries the next block, so a single column can support a wide overhanging eave and the whole frame can flex under wind or earthquake load rather than crack. The density and tiering of a building's bracket sets was also a marker of rank, reserved by convention to imperial and the largest religious halls.
