According to legend, there are five types of phoenixes, namely the red Suzaku, the green Qingluan, the yellow phoenix, the white swan and the purple eagle.
Ancient books record that the eagle is such a bird. They always fly together, male and female, and are more affectionate than mandarin ducks. When one of them dies, the other wails for three days and nights. Finally, the hot blood becomes cold and the blood dries up, and it becomes as good as the nine springs.
