During the Tang Dynasty of China, dust rose up at the entrance gate of the city

During the Tang Dynasty of China, dust rose up at the entrance gate of the city, making it difficult to see. The fog obscured the figure of a young man in monk robes, his four-tone robes covering his body from the dust. He was walking towards the entrance gate of the city. A young woman in a dark brown general's robe was standing in front of the city gate waiting to greet him. The atmosphere of the dust made it difficult to see anyone walking.
