u1 u2 u3 u4, If you would like to practice "u", try to pronounce number 五（5）。 The place to pronounce is in the mouth, not the vocal cords. 你好！我有很多日本的学生。我的经验是，多数日本学生不是发不出 u 这个音，而是不太会发 h f 这两个音。比如你说的“组合” 和”符合“ 发音的区别不是在韵母 u 上，而是在声母 f, z 上。很多同学把”符合(fu he)"读成” hu he" 。就像英语中very 会读成 berry一个道理。纠正这个发音，需要练习如何正确发出声母的音。 Hope it would help you.

its pronunciation is similar to Japanese "u" , but you need to bulge your lips slightly exaggeratedly

Please pay attention your mouth shape when saying “u”，which like a small circle“o”.

符合“…accord with…”“…be accordant to…” 如何“how…”“how to …”“what about …” 组合 n.combination adj . combination v. compose

So it's "Thank you for your information, Alyssa." and "but they are so different" for me. Well, are never knew Japanese people are so double-faced, saying two opposite opinions about one thing. Were are your 9 comments? Deleted due to shame?
