Photo taken on Feb. 13, 2019 shows oil tanks with paintings of Peking Opera facial make-ups at the Zhongshan Station, a Chinese research base in Antarctica. The Zhongshan Station, set up on Feb. 26, 1989, was the second of four scientific research bases on the Antarctic ice sheet built by China since 1964. Today it remains a logistical transit hub for inland expedition on the icy continent. Over the past 30 years, the Zhongshan Station has grown into a modern "scientific town" in Antarctica and can provide logistical services for fixed-wing aircraft, according to the Chinese expedition team.
