Wu Tingting, 42, the first female doctor in China's polar expedition teams, clearly remembers her marvelous journey 15 years ago.

In 2010, Wu was a surgeon at a top hospital in Shanghai when she was fortunate enough to seize the opportunity to join China's fourth Arctic expedition and the 27th Antarctic expedition.

Generally, male surgeons are dominant in hospitals, as was the case for the polar expedition teams, mainly due to physical strength and endurance in extreme climate conditions. However, it does not necessarily mean that females are not able to qualify for either position. Instead, their unique features and traits add color to the journey, demonstrating the vigorous female power of pushing the polar limits.

"We all have our strengths and weaknesses. As female doctors, we tend to be more attentive and can observe the subtle changes in our members faster and better, especially when it comes to mental health," says Wu.
