Editor's note: As the northernmost offshore oil-drilling rig located in China, the Liaodong Bay-based Jinzhou 9-3 oil-drilling rig is encircled by sea ice between December and March every year. The depth of the ice cover reaches as thick as 20 to 40 centimeters in the -20 degrees Celsius. To ensure sound drilling, a 100-strong icebreaking team lives on sea to keep ice at bay.
