Winter solstice solar terms are good words.

Winter is coming! Winter is like a clean little girl, all white, and even the curtains have changed from gold to white. Wearing a white velvet hat, white velvet trousers and a pair of white leather boots in winter is like a lovely white velvet ball. With chubby little hands, she directed snowflakes to fly to the earth to clean up the dirt there. Snowflakes obediently obey the command of winter, dancing their beautiful hexagonal bodies and falling on the earth. In a short time, the earth was white and turned into a snowy world.
