"White Horse and Dark Horse" tells us that appearance is not important, what matters is inner quality and ability. Although the little black horse is ugly, its mother told it that as long as it grows up, it has the strength to help the shepherd put the sheep away, whether it is black or white. The little black horse listened to his mother and became very brave. Finally, he grew into a tall and beautiful mare. This story makes us understand that we should be a good boy who is obedient and sensible, and also have the love of our mother. At the same time, this story also compares the "soul carriage" of human beings, which is pulled by a white horse and a dark horse. The "white horse" leads the soul to the road of balance, moderation and truth, and the dark horse represents the passion of human beings, which is the root of injustice and chaos. Therefore, we should pay attention to internal cultivation and quality, not external appearance.
