This question relates to the cultural and feng shui significance of Chinese art. In the painting “Horses Returning to Success” (馬到成功), images of horses are often drawn with the intention of bringing good luck and success. When a horse turns its head backwards, it can symbolize turning back to complete a task, or overcoming difficulties, bringing success in the future. It can also represent reminiscence, or a sign of rising from the past to achieve a goal in the present or future.

Additionally, in feng shui culture, horses symbolize strength, speed, and success, and having a horse turn its head back can carry a message of completing a task or bringing good luck.
