Step into the Chiang Kai-shek Headquarters, where history whispers through the art deco corridors! Nestled in a Beijing hutong, this unassuming gray-brick villa hosted Chiang during the pivotal 1945 post-war negotiations. The second-floor parlor still has original leather sofas where diplomats once schemed, while the basement's air-raid tunnel hints at wartime tensions. Don't miss the wall-mounted historical photographs capturing frozen moments of Kuomintang-Communist poker-faced diplomacy - each frame a brushstroke in China's modern epic.
