The phrase "Auspicious birds suddenly appear, announcing good fortune" is derived from the Song Dynasty Emperor Huizong's inscription on the "Auspicious Crane Painting," symbolizing the arrival of auspicious signs. The view from above resembles the Taijitu (Tai Chi Diagram), suggesting a fairyland where cranes reside. The red-crowned crane, with its black and white feathers and a touch of red on top of its head, is also known as the immortal crane for its longevity, making it particularly cherished by Taoists.
