The book is of great significant as the final part of Yang Yankang's Faith Trilogy. Yang expands the scope of experimental exploration of the language of modern Chinese photography.Star and Moon presents the daily life of the Hui people and expresses a kind of “emptiness” that transcends time and meaning. Lonely, mysterious, quiet and elegant, the simple images are like a faded postcard, bringing a deep Zen feeling to the heart. At first glance, the images of Star and Moon are plain and seemingly picturesque. However, if you sit quietly for a moment and feel the breath conveyed by the black and white shadows, you will experience a heavy breath running through it, adsorbing the viewer's eyes tightly, following the photographer's lens in the cycle of the stars and the moon, experiencing the destiny of the Islamic nation together. Yang Yankang expands the scope of experimental exploration of the language of modern Chinese photography, and creates a revelatory way of perceiving the art of practical photography. His works on the three major religions have historically placed them in a prominent position in the history of modern Chinese art, and he has become one of the leading photographic artists in China and even in the world.
