If you're wondering about sichuan vs szechuan this is another case of pinyin vs wade-giles romanization. Same word, same pronunciation. Pinyin is objectively better, also the modern standard.
Lemme say, sichuan seasoned meatloaf is the best.
(I bake a meatloaf using impossible burger as the base, seasoned with doubanjiang, chili crisp, five spice powder and sichuan chili powder. In both the loaf and the sauce.)
Beijing and Peking are also an example of this. Which, if you ever listen to the actual Mandarin pronunciation, really drives home how weird wade-giles is.
