The ice ground is too slippery in winter. It's very unlucky that our princess Elsa accidentally fell on the slippery ground. Her neck, arms, and legs were badly injured and needed urgent surgery. Clean and bandage the wound for her to avoid infection, take X rays for her to see if there is any bone injury, and provide timely treatment to help her recover. Don't forget to dress her up for the winter ball after her recovery. Have fun!
