September 30 is Martyr's Day in China. This year marks the 90th anniversary of the victory of the Long March. Ninety-two years ago, the Chinese Red Army, the forerunner of the Chinese People's Liberation Army (PLA), carried out the Long March, a military maneuver from 1934 to 1936. 

At the Long March Culture Digital Art Museum in Guiyang, southwest China's Guizhou Province, CGTN's Mi Sutong stepped into "The Great Expedition," an immersive show that brings the historic journey to life through live actors, giant screens, real-life sets and sound.

From snow-covered mountains and grasslands to raging rivers, battles, farewells and moments of sacrifice, the experience puts visitors in the middle of the journey.

Ninety years on, how can we look back on the Long March in the digital age?
