根据金尼阁对“甚、次、中”的解释,通过分析u韵各小韵的代表字,认为《西儒耳目资》的“u次”不是舌尖前高元音,而是一个与“u”相近的音。而根据现代方言,可以将“u次”拟作[y],“u甚”拟作[尬],“u中”拟作[u]。 According to the interpretations of “even, twice, and” by Kinnige, it is considered that the “u times” of “Xi Ju Er Tou Zi Zi” is not the vowel of the tip of the tongue but an “ u ”sound similar. According to modern dialects, “u times” to be made [y], “u very” intended to make [awk], “u in” to be made [u].
