Here’s a map – rather roughly hand drawn – entitled Yunnanfu (now Kunming) across to the coast. It was published in Shanghai in the North China Herald on December 9th 1904. There’s a lot to notice obviously – the boundaries of Yunnan province with French Indochina as well as the borders with the provinces of Kweichow (Guizhou) and Kwangsi (Guangxi). Kunming Lake is included in the top left and the route to the Yangtze. You can look up the others. Yunnan at this time was a tin mining centre so commodities were important over a century ago!!
