Tone labeling rules of Chinese Pinyin;
A, O, E, I, U, U are marked in turn, I and U appear at the same time, and the vowel after the mark will be removed when U touches J, Q, X, Y. As long as there is an A in vowels, mark it on A, if there is no A, find O and E, if there is an O, mark it on O, and if there is no O, mark it on E.
If there are two vowels (vowels), and the first vowel (vowel) is I, U or U, the tone is marked on the second vowel (vowel). In other cases, the tone should be marked above the first vowel (vowel).
