In January and February the world’s largest ice festival takes place in the city of Harbin, in Northeast China.

7,000 artists and workers have been working putting the finishing touches to the annual Ice Festival grounds.  

The main picture above shows an ice piano, playing when you walk on it.

The ice-blocks are illuminated in different colors at night.

Globalo-Founder Hubertus Hoffmann (pictured below) took these pictures with impressive colors and sizes at minus 32 celsius.
