The mark consists of three parts: a circle, a crown and a bird. The bird's body is inside the circle, its head is horizontal to the right, and its eye is in circle. The bird's tail is on the bottom right outside the circle and is connected to the circle. The tail has a certain inward curve at the bottom. The crown is at the top left. The distance between the crown and circle is about the diameter of the bird's eye. The crown has three sharp corners, each of which is set with a round stone of the same size, the middle corner is the largest in height, and the two sides are the same size. The line on the left side of the crown, the line on the right side of the bird's body and the line above the tail are parallel. The beak is a sharp triangle, and the Angle of the sharp corners is the same size as the sharp corners on either side of the crown.
