A Chinese couple with a penchant for adventure are planning an 80,000-kilometer round-the-world trip that will see them fly themselves to five continents, including Antarctica.

Zhang Xinyu and his wife, Liang Hong, plan to begin their journey by flying a Chinese-made plane from Harbin, capital of Heilongjiang province, to North America via the Russian Far East.

Their itinerary will take them to the Mexican Plateau and Chile's Atacama Desert before they arrive in Antarctica. Afterward they plan to fly to Africa via Brazil's rainforests, visiting Ethiopia and Kenya, before eventually returning to China via Southeast Asia, completing a journey that is twice the length of the equator.
