Yellow, as the earth color in the Chinese Five Elements Theory, symbolizes fertility, prosperity and stability. Therefore, as a cultural symbol, the yellow dog is often used to represent loyalty and prosperity.

In ancient China, fair skin color was regarded as a sign of beauty and health. People with fair faces often give people the impression of being gentle, kind and benevolent.
