Chinese character 翢

It depends on the reading: a banner or a bird.

In classical texts, the banner sense names a large standard decorated with feathers. Dictionaries gloss it as 纛; an old gloss describes a feathered staff carried by dancers.

In the old Chinese text Han Feizi, 翢翢 is a bird with a heavy head and bent tail. It drinks by gripping its own feathers. These are two documented classical uses; the surrounding text tells which one is meant.
