It's a big bird, transformed into Peng by the northern style.
The golden-winged Dapeng mentioned by Buddhists is actually a Goluda bird with beautiful wings. It is the descendant of Brahma, the courtier of Luona Yantian, and feeds on dragons and snakes. On the day this bird died, the poison of dragon and snake broke out, and the body was burned up by the poison flame, but the heart turned into a pure blue glaze treasure.
Because these two birds are very big in appearance, the Gruda bird is nicknamed Dapeng with Golden Wings in China.
