Road through the Qinling
Baoxie plank road cut cliffs with holes, posts and boards—one of four named Hanzhong crossings south from Chang'an.
Hanzhong belongs to the southern Qinba mountain belt, south of the Qinling that Shaanxi calls China's north–south climate divide. Rivers here feed the Yangtze system. Ancient corridors from Chang'an crossed the range on cliff-hung plank roads; Mian County keeps Zhuge Liang's burial on Dingjun Mountain apart from the nearby temple town.
