You either get the symbols from sixman groups (which I normally lose the roll on anyway) or by farming certain animal types or mobs in paikang. I've had them drop from sharks, quillons and the dragon soldier mobs as well as the ape boss mobs. Haven't seen any drop from firebirds or fu dogs so I don't know if they drop the things.
Some quests also give the symbols, such as insurrection.
