Around 100 sculptors and workers spent more than 20 days constructing an ice sculpture of the CNS Liaoning aircraft carrier on the frozen Songhua River in Harbin, Heilongjiang province.

Built at a scale of 1 to 6, the sculpture used 350 metric tons of ice, measuring 72 meters long, 15 meters wide and 13 meters tall.

"Different from traditional ice sculptures, it was built on a barge base with a steel structure as the framework, and the external shape was constructed by ice blocks," Chen Rongxin, designer of the sculpture, told Jiupai News. 

During the construction process, the team modified its plans several times based on the ice's bearing capacity and the ship's load to ensure the construction's safety, scientific accuracy and aesthetics.
