Write a story about winter to encourage children to fall in love with winter, and at the same time popularize science about the principles of skates, snow tires, the rotation and revolution of the earth, and what is transparency? To do science popularization for children around 4 years old, since there is no comprehensive science popularization, let's start with the cuteness of winter and introduce a bright winter. Instead, it brings in basic winter science knowledge that a 4-year-old child can understand.
Concept: Children don't go out to play in winter. They always like to watch TV at home, telling them that winter is also very cute.
