Tangshan City in north China's Hebei Province, leaning against the Yanshan Mountains, facing the Bohai Sea, and abutting Beijing and Tianjin, is the cradle of China's modern industry, a recovery miracle after the horrific earthquake in 1976 and also the hometown of Li Dazhao, a co-founder of the Communist Party of China (CPC).
