South Pole team gives colleague a special birthday

Wang Nan celebrated her 25th birthday on the frozen continent of Antarctica. She didn't go there on an ordinary trip. Instead, she was one of the youngest females on the national expedition team.

Wang, who does publicity work at the Shanghai-based Polar Research Institute of China, joined a 159-day Antarctic expedition on the Chinese icebreaker Xuelong (Snow Dragon) in November 2015. It was the country's 32nd Antarctic expedition.

She said an extraordinary birthday celebration at Zhongshan Station, a Chinese scientific research base in Antarctica, will be in her mind forever.
