The 30th Harbin International Ice and Snow Festival opened in Harbin, capital of northeast China’s Heilongjiang Province on Sunday night. Harbin’s ice and snow tourism industry has developed for 50 years since 1963. Over 7,000 artists and workers have been working around the clock putting the finishing touches to the annual Ice Festival grounds. Harbin International Ice and Snow Festival features huge sculptures of famous buildings, a gigantic 240-metre-long ice slide and even a loving tribute to Dutch artist Florentijn Hofman’s globe trotting rubber duck. These ice sculptures are of famous characters from cartoon and comic books of different countries.
