然rán

然 (rán, "correct, so") remains unchanged from traditional to simplified, a rare character that survived the reform intact. Its structure places a dog (犬) beneath fire (灬), originally depicting a dog being roasted — an ancient method of divination — and evolving to mean "like this" or "as it is." In contemporary Chinese, 然 appears in adverbs like 虽然 (although), 突然 (suddenly), and 自然 (nature), always carrying that sense of "being so" or "turning out that way."
