What is the sunset genre of the Yellow River?

Wang Weiyou, a poet in the Tang Dynasty, said that "the desert is lonely and the smoke is straight, and the long river sets the yen". The sunset in the long river of the desert beyond the Great Wall described in the poem gives people a magnificent and rough beauty. Sunrise and sunset are a genre in which photographers often shoot landscapes. I remember a master photographer said that shooting sunrise or sunset can only give you the best shooting time of about ten minutes at a time. You will regret if you miss it.
