Anotations

Scope note:

The earliest known use of the term huagong 華栱, literally, “blossoming bracket-arms” (Kroll 2015, 167 (huā), 135) or “flower arms” (Fu 2017, 357), is in the Yingzao fashi (YZFS 4.2b-4.3a). As an architectural term, huagong refers to any bracket arm in the bracketing structure that projects away from the wall plane.
