Every year, from January 5th to around February 25th, the city of Harbin, China transforms into a frozen city of light for the annual Ice and Snow Sculpture Festival. The sculptures are massive architectural feats constructed in -15 degree Celsius weather… rainbow castles, illuminated towers and pyramids, snow animals, cartoon characters, and more. It’s spectacular.

Meet ice sculptor and art teacher Jinnan Zheng and see the tools he uses to carve his award-winning contributions to the festival in this video from Great Big Story.
