Jinggangshan, the "cradle of the Chinese revolution", is China's flagship red-heritage training base. Standard programs run 3–5 days and pair classroom sessions with on-site teaching at Huangyangjie (the 1928 defence battle), Octagon Tower (where Mao wrote "Why Is It That Red Political Power Can Exist in China?"), the Martyrs Cemetery, the Revolutionary Museum and the Longtan waterfalls. Packages include coach transport, instructors, Red Army uniforms, accommodation at training centres, opening and closing ceremonies, certificates and group photography; medical backup and roll-call checkpoints run throughout. Custom modules cover team building, corporate culture and youth education. Ruijin and Yudu (where the Long March began) can be added as a 2-day extension.
