The difficult, year-long journey made by Mao Zedong and his Communist followers in 1934 through China’s mountains, marshes, and rivers was called the Long March. Option 4 is correct.
The Communists, conducted by Mao Zedong and Zhou Enlai, ran away in a circling retreat to the west and north, which traversed over 9,000 kilometers (5600 miles) over 370 days.
