- mikeash 10y ago"Sichuan" is how the name is romanized using Pinyin, which is now more or less the standard romanization for Mandarin. "Szechuan" is from the older Wade-Giles system, and I think "Szechwan" is just a variation. The rise of the "Sichuan" spelling on your graph roughly corresponds to the rise of Pinyin.
