Wei Jinhua, who comes from East China's Jiangxi province, invested 50 million yuan ($7.18 million) to reinvent an underground garage into the largest indoor ice and snow world in northwestern China.

"Since the ice-making plant in Xi'an, Shaanxi province, does not have large ice chunks, ice used here - more than 2,000 metric tons - is transported from Wuhan and other places," Wei said.

The ice and snow world in the Qujiang Polar Ocean Park in Xi'an consists of three parts - ice sculpture exhibits, a parent-child interactive experience and a winter sports show. More than 500 pieces of ice and snow works were carefully carved by over 40 ice sculptors, who worked eight or nine hours a day in a large ice house at minus 8 degrees Celsius, with a wage of 1,500 yuan per day.
