In ancient Chinese, "ping" refers to floating objects on the water surface, while "rain" is a natural phenomenon in nature. So some people define "jade screen" as natural objects such as leaves, flowers or branches floating on the water in rainy days. When these objects are wet and washed irregularly in rainy days, they will also give off a different kind of fresh breath, giving people a double feeling of sight and smell.
In some novels, songs and poems, people also use "jade screen" to describe women. Because Yuping represents a strong maternal love and care, the word Yuping often appears in the description of female images in these works. For example, they are gentle and kind-hearted, especially when facing the family, and they will be as loving, tolerant and supportive as Yuping.
