Explanations in Shuo Wen Jie Zi: Rong Ye. From the heart. All people who think belong to thinking.
Rain: rain, water falling from the clouds to the ground.
"Shuo Wen Jie Zi" explains the cloud: Water comes out from under the cloud. As the sky is like a cloud, water is idle. All rain belongs to rain.
The meaning of the name can be interpreted as: "Look at the mountain after the rain, and look at the moon god before the wind".
