Fou Guang temple, built in 857, Tang Dynasty, is the oldest surviving building in the China. It's a single-eave and four ridges roof building. The width has seven bays and the depth has eight shelf rafters. The column-top corbel-bracket set is really different from the corbel-bracket set  between two columns, and also more complex.
  As the typical building of Tang Dynasty, its corbel bracket sets are sturdiness. The scale of  the height of column and width is similar to a square and the height of Tou-Kung is almost same as 1/2 height of column.
