Anotations

Scope note:

Chagong 插栱, which cannot be found in traditional Chinese literature, is a term translated by Liang Sicheng from the Japanese sashihijiki 挿肘木. Sashihijiki refers to the bracket arms of the outer eaves of the South Gate of Todaiji Temple in Nara, Japan, which are directly inserted into the pillar shaft (Tanabe, Liang (trans.) 1932).
