Question: are sichuan and szechuan the same?
Answer: The “Sichuan” spelling is Pinyin , or the preferred romanization used in the People's Republic of China. The “Szechuan” spelling is from the older Wade–Giles romanization, used in Taiwan, most of the West until about 1985 or so, and by many Chinese immigrants who left China during the 1940s and 1950s.
