With 190-day freezing season, the northeastern city of Harbin is known as a "City of Ice" and a cradle of the ice-and-snow culture in the world. The long and frigid winter, and the high plasticity and hardness of ice blocks quarried from the Songhua River, furnish favorable conditions for ice and snow sculpture. On January 5, 1985, the first Harbin Ice and Snow Festival was unveiled. Since then it has become an annual event, which is highly acclaimed around the world. Harbin was also the venue of the Third Asian Winter Sports Tournament.
