He painted horses to express his feelings, beliefs and pursuits with the help of the horse's momentum. Horses are wild, docile, brave, loyal and hardworking, which are closely related to the artist's artistic personality. Xu Beihong painted horses with emphasis on their style. The lines are concise and bold, wet and dry are distinct, the thickness is appropriate, and the coloring is slightly concave and convex. This is a successful attempt to integrate Chinese and western painting methods. Ma Tu, Ben Ma Tu and Ben Ma Tu are his representative paintings of horses.

The wild horse in Running in the Crowd is unrestrained and full of vitality, which pours into the painter's thoughts and feelings of longing for freedom, embodies a magnificent spirit and exudes the spirit of heroism. Xu Beihong was living in India when he created this painting. He learned from the newspaper that the Japanese army defeated the Japanese invaders in northern China, and painted this wonderful painting on a whim. He used this picture of a herd of horses to express his hope for the country and the nation and his belief in the victory of the Anti-Japanese War.
