Story scene.
A child came to a palace in his dream and a girl came out to meet him. She introduced herself as Wang Xiaoling and wanted to show him around her Zero Kingdom. The citizens here have shaved their heads. You can shake hands with them safely, but you can't hug them. A handshake is like a plus sign. You are still yourself. Hugging is like multiplication.
