"Shiwei, where do you think the gate to heaven is?"
"If there is one, it should be behind the clouds."
"Yes, we all know that there is another world in heaven, where the souls of good people rest."
"Well, I say so. There is a world in the sky and a world on earth. It's just that the one in the sky is called heaven and the one on the earth is called the world of mortals."
"Then do you think we will get lost in the sky in the future? The sky is so big, and there is no sense of direction at all."
"Then just tie a yellow ribbon on the cloud!"
