China's first domestically built polar icebreaker, Xuelong 2, which translates as "Snow Dragon 2", and China's independently designed and built icebreaker research vessel, Jidi, berthed at the pier of the Qingdao Olympic Sailing Center in Qingdao and started an open-house event there on July 3.

Jidi is a new-generation icebreaking survey ship independently designed and built by China. It was officially named and delivered on June 24 and opened to pubic visitation for the first time.

After the opening day, the 14th Chinese Arctic Expedition Team, including the Xuelong 2 and Jidi, will set sail from Qingdao for their expedition.
