Finding Chinese Character Sounds

From Kingdom of Characters: The Language Revolution That Made China Modern, by Jing Tsu (Riverhead Books, 2022), Kindle pp. 25-26:

As part of a serious education, any learned Chinese down to Wang’s time [c. 1900] would have had to master the reverse-cut method for learning how to pronounce characters. Reverse-cut first appeared in the third century and remained in use until the early twentieth. Each Chinese character has a one-syllable sound associated with it, and all syllables have two parts: an “initial” (the consonant sound that begins a syllable) and a “final” (the rest of the syllable sound). For a guide, a novice would turn to a rhyme book, which functioned like a dictionary of pronunciation. In it, the sound of each listed character was “spelled out” by cutting together two more commonly used and familiar characters. One character’s initial sound was added to another’s final sound to indicate the pronunciation of the character in question. To pronounce the character for “east” 東 (dong), for instance, you would look up 東 in a rhyme book and it would tell you that the pronunciation is the initial of “virtue” 德 ([d]ek) combined with the final of “red” 紅 (h[ong]).

This technique used the phonetic parts of two known characters to sound out an unknown third character in the same way that (5 – 3) × (1 + 1) conveys the number 4. That’s a complicated way to arrive at 4 if all you want is the number.

The old reverse-cut phonetic system solved many problems—like accommodating the translation of the exotic sounds of Sanskrit when Mahayana Buddhism’s scriptures were introduced into China in the late seventh century—but now it had itself become the problem. It required years of rote memorization to learn and was no longer accurate—speech habits had drifted and evolved over time. “Virtue,” for example, is no longer pronounced as “dek” but as “de” in modern-day Chinese. Pronunciation also differed wildly between dialects.

The Chinese spelling system was woefully outdated. At the same time, the Western alphabet was viewed with suspicion in a climate of hostility to foreigners. A middle path had to be found. People like Wang [Zhao] realized there needed to be a system that acted like an alphabet for Chinese without simply using Roman letters.
