A helicopter carrying part of China's 34th Antarctic expedition members arrives at the Inexpressible Island in Terra Nova Bay of the Ross Sea, Antarctic, Dec. 7, 2017. By 3 a.m. on Dec. 10, 2017, materials weighing 250 tonnes were transported to the Inexpressible Island, where China plans to build its fifth station in the Antarctic in next five years. The new year-round research station will fill in the blank left in China's antarctic research since the Great Wall and Zhongshan stations cover different directions, one towards the Atlantic and the other towards the Indian Ocean.
