孝 乌 filial piety Chinese
Totally OT: Crows were called 孝鸟 by ancient Chinese because it was said that when their parents get too old to fly, they would care for them and regurgitate food to feed them like their parents did before. Thus they are much admired in ancient China. There is actually a grain of truth in this because zoologists do find that crows visit their parents many years after they left. – Wang Dingwei Aug 5 at 4:22
