The photos show the subway in Korea. It look very comfortable and nice.

Officially, the festival starts from January 5th and lasts one month. However often the exhibitions open earlier and last longer, weather permitting. Ice sculpture decoration ranges from the modern technology of lasers to traditional ice lanterns. There are ice lantern park touring activities held in many parks in the city. Winter activities in the festival include Yabuli alpine skiing, winter-swimming in Songhua River, and the ice-lantern exhibition in Zhaolin Garden. Snow carving and ice and snow recreations are world famous.
The Harbin festival is one of the world's four largest ice and snow festivals, along with Japan's Sapporo Snow Festival, Canada's Quebec City Winter Carnival, and Norway's Ski Festival.
