This year marks the 90^th anniversary of the end of the Long March. From 1934 to 1936, the Red Army endured an arduous journey across China, leaving an indelible mark on the country's history. Along the way, bonds between soldiers and local communities gave rise to stories of trust, gratitude and sacrifice. In Chenzhou, Hunan Province, CGTN's Cao Chufeng brings us one such story, passed down through generations.
