Meanwhile, Harbin Polarpark debuted its penguin parade in late December, featuring 20 rare Antarctic penguins at its square.

Visitors can watch the daily parade for free, as well as new beluga whale and dolphin shows.

According to a tourist from Hunan province, "the excitement of watching the penguin parade made me feel my whole trip to Harbin was worthwhile."

Experts said the authorities in Harbin, and throughout Heilongjiang, need to seriously consider ways to promote the long-term sustainable development of ice and snow tourism.
