In early 1928 Zhu De's troops, survivors of the Nanchang Uprising, Little Long March and Battle of Shantou, found refuge here with the local warlord. Chen Yi was with him; neither dared reveal his identity at the time. It was from here that a rested and bolstered communist column marched to the Jinggangshan Mountains in April to join the hold-outs from another uprising.
