Meanwhile, "the Menggu-Ziyun (蒙古字韻, Mongolian Letters arranged by Rhyme)" edited by Zhu Zongwen (朱宗文) in late Great Yuan Dynasty (in 1308), which was a rhyming dictionary of Chinese ideographs arranged according to phonetic syllables written in the Phags-pa script, categorized '日' as the entering tone of ži, and '本' as the rising tone of bun, and '国' as entering tone of guų respectively.
一方、同じ大元朝時代にパスパ文字と漢字音を対応させた朱宗文撰の韻書『蒙古字韻』（1308年）によると、「日」はžiの入声、「本」はbunの上声、「国」はguųの入声にそれぞれ分類されている。
