Between January and March 1935, 30,000 CPC-led Central Red Army troops faced 400,000 Kuomintang-led forces in pursuit and encirclement. The Red Army crossed the Chishui River four times, using swift maneuvers and sudden shifts to keep their pursuers off balance.

CGTN anchor Zhong Shi and reporter Zhu Siying return to the river crossings and mountain trails to explain how this campaign restored the Red Army's morale and helped it gradually gain the initiative on the battlefield.
