caption: The image shows a painting of a man riding on the back of a black horse, holding a stick in his hand. The painting is accompanied by text written in Chinese characters, likely describing the scene. The man is wearing a traditional Chinese outfit, with a long robe and a headdress, and the horse is galloping forward with its mane and tail flowing in the wind. The background is a deep blue sky with a few clouds, and a few trees in the distance.
