86 hours-- A legend of Antarctic expedition (8)

China's icebreaker Xuelong was blocked by a one-kilometer-long iceberg after rescuing passengers on a Russian vessel stranded in Antarctic. The scheduled 8-day expedition mission then was delayed. China's Antarctic expedition team members had to save every second to do the research for the preparation of China’s new Antarctic station and finally accomplished it in 86 hours, which could be seen as a legend of Antarctic expedition.
