8. Vowels 4
ɑi ei ɑo ou ɑn en ɑng eng ong
i iɑi iɑo i(o)u iɑn in iɑng ing iong
u uɑi u(e)i uɑn u(e)n uɑng ueng
ü üɑn ün
Remember to go to
the pinyin to listen
the proper sounds of
the vowels.
9. Tone mark rule:
“i, u, and ü” cannot be marked unless
they are by themselves. If two
vowels that start with “i, u, or ü”,
place the tone mark on the top of
the 2nd
vowel.
Ex. “níng” or “tú”
niú or huān
