Note: Rhyme dictionaries all provide the pronunciation as yi (falling tone). The Correct Characters Guide (Zhengzitong) reads it as the sound of xi, which is incorrect.
Verification: The Tang Rhymes (Tangyun) provide the pronunciation as yi (falling tone), and the Collected Rhymes (Jiyun) provide it as yi (falling tone), with the same reading as the character for shadow (yi).
Critical analysis: The character Yi belongs to the ji rhyme category, while the character for meaning (yi) belongs to the zhi rhyme category. Yi and yi are not pronounced the same. According to the Extended Rhymes (Guangyun) and Collected Rhymes (Jiyun), the reference to the character for meaning (yi) is hereby corrected to the character for shadow (yi).
