English: A clear version of a small French National Library scan of Dufour's 1840 "Map of China and Its Tributary States", used in Huc's 1853 2nd edition of his Remembrances of a Voyage in Tartary, Tibet, and China during the Years 1844, 1845, and 1846 with a dark line tracing the route of Huc and his fellow missionary Joseph Gabet. Note that this line is correct and includes his sea voyages, as opposed to the erroneous route traced in the 1st edition which confused Huc's route with Dufour's illustration of the Grand Canal.

The Yellow River is still shown following its lower course from before the massive floods of the 1850s.

Shanghai is entirely omitted as less important than Hangzhou (Hang-tcheou), Suzhou (Sou-tcheou), and Songjiang (Song-kiang, entirely misplaced to the north bank of the Yangtze).

Some important places along Huc's route have been marked in the map and noted in a legend at the bottom of the page.

Note that Huc & Gabet did not carry Dufour's map but one of those printed by Andriveau-Goujon like this.
