"Five Emperors": "The heaven has five elements, water, fire, metal, wood, and earth, which are transformed and nurtured in time to create all things."
The five elements generate and inhibit each other, forming a circle and inhibiting each other, forming a five-pointed star. This is the understanding of the Yin and Yang family!
When Lu Tu was young and ignorant, he was curious about everything. When she was chatting with her grandfather in a courtyard in the village, she heard a grandfather with gray hair talking about the Five Elements. Lu Tu couldn't understand and asked her grandfather: "Grandpa, what are the Five Elements? What is the old lady talking about?" Her grandfather thought for a long time and drew a five-pointed star on the ground outside the five-pointed star. A circle: "Atu, look, there are five corners here. These five corners are metal, wood, water, fire, and earth. They are mutually reinforcing and interfering with each other, which means they help each other and make trouble for each other!" Little Atu can't understand mutual interdependence, but she knows what her grandfather said about helping and making trouble! "Ah, I understand. They are just like me, brother Kun, Yi Yu, Li Tao and Xiaoting. We help each other and make trouble for each other!" Lu Tu's explanation made everyone present laugh, and they all said that children's words are unbridled!
