Four years after establishing the Great Wall Station, China's first research base in Antarctica, Guo Kun led another expedition to Antarctica, with the mission to establish a second base. The team set out from Qingdao in November 1988 on the ship "Jidi". After reaching Prydz Bay in Antarctica, the ship encountered a major icefall in the night of 14 January 1989. She missed being directly hit by ice by just two or three meters, and became trapped by icebergs for seven days. Many team members wrote their wills and were ready to die. Luckily, the icebergs shifted on the seventh day and temporarily created a 30-meter-wide opening, and the team seized the opportunity to escape from the trap. The opening lasted for just two hours before being closed again. The team proceeded to construct the Zhongshan Station at Prydz Bay in only 28 days, and it was opened on 26 February 1989.
