Taoist symbolism. Eight Trigrams Furnace. FengHuang ( the "Phoenix" ).
I don't know what the Chinese characters translate to (the English translation … Can be taken as a surface meaning, Eastern languages love playing games with the histories and meanings of their characters) - but what I can read is the Taoist symbolism. Note the spiral at the center beneath the FengHuang. That is an ancient way of depicting the Taijitu - the "yin-yang."
The fact it is also a bull seems to be a more minor symbolic element, as everything else is the Eight Trigrams Furnace. Well… The FengHuang are in there - which is, perhaps, a nod to the Empress. Or maybe the wives of some heads of state. But I have not hit on anything and must workfag soon.
