Hong Kong today welcomed the nation's first domestically built Antarctic research icebreaker Xuelong 2 and the 40th Chinese Antarctic scientific expedition team for an historic five-day visit. 

Xuelong 2 is equipped with advanced marine and polar research facilities, including a data acquisition and detection system for the collection of seawater samples at various depths.

It is also the world's first icebreaker to adopt bidirectional and 360-degree free rotation technologies, enabling the vessel to navigate icy waters more efficiently. The ship also features a helicopter for emergency rescue and essential supplies delivery.

The vessel will be open for registered citizens and groups, offering the public an opportunity to explore the advanced facilities onboard, while its crew members and scientists will join sharing sessions with Hong Kong students.

A series of events is being held to commemorate the vessel's visit, including a free exhibition at the Science Museum that will run until June 26, for the public to gain a deeper understanding of polar research and the role of Xuelong 2.
