I stumbled upon "于闐" (Yutian) one time. Naturally, I looked up its history and culture. And then I found out that it is called Khotan in English. "Yu" and "Kho" sound very different. Then I started looking into sound changes. One thing led to another. In summary, the focus of this diagram is about 4 groups of consonants, /k/, /h/, /j/, and /∅/, plus 2 other secondary groups. Please start with the transition path sub-diagram on the lower-right to understand the primary sound changes in history.
