烏鵲（上隖姑反說文云孝鳥也下七雀反知太歲所在也博物志曰鵲巢開門常背太歲此非才智任運自然說文二象形字也）。

Crows and magpies (烏鵲: the upper character is wu + gu fan. The Shuowen jiezi says: the filial bird. The lower character is qi + que fan. It knows the location of the Grand Year (Taisui). The Bowuzhi says: A magpie opens its nest's door always facing away from the Grand Year; this is not due to cleverness, but occurs spontaneously according to nature. The Shuowen jiezi states that both are pictographic characters).
