The promotions can be summarized as series of promotion chains, as follows. Within each block below, a piece (except the kings) promotes to the piece above it. Pieces at the top of each block do not promote (and if in italics, and with an *asterisk, as stated before, these appear only upon promotion). Note that pieces may only promote once. For example, a gold general promotes to a rook, and a rook promotes to a dragon king, but a gold general promoted to a rook cannot promote a second time to a dragon king. This is clear from the equipment, for each piece only has two sides.
