拼音读写规则
The rules of writing and pronouncing the Initial-final combinations
The rules of pronunciation
1.z 、c、s或zh、ch、sh、r后面的i永远不能读[i]，而应当读作[ɿ ] 或[ʅ ]，如：si [ s ɿ ] 、shi [ʂ ʅ ]、ri [ ʐ ʅ ] ；
The final ‘i’ following the initials z, c and s cannot be pronounced as [i], it should be pronounced as[ɿ ]. And when the final ‘i’ is behind the initials zh, ch, sh and r, it should be pronounced as [ʅ ].
For example: si [ s ɿ ] 、shi [ʂ ʅ ]、ri [ ʐ ʅ ] .
2.j、q、x、y后面的u永远不能读[u]，而应当读作[y],因为实际上这个u只不过是ü的变化形式，如：ju [ʨ y]、 qu [ʨ‘y] 、xu [ɕy]和 yue [yɛ]。
The final ‘u’ following the initials j, q, x, and y cannot be pronounced as[u], it should be pronounced as[y]，because in fact this u is only the transformation of the ü . For example: ju [ʨ y]、 qu [ʨ‘y] 、xu [ɕy] 和 yue [yɛ]。
3.写成iu、ui、un的韵母，实际是iou、uei、uen的缩写，只能读作[iəʊ]、[uəɪ]、[uən]。如：niu[n iəʊ]，sui[s uəɪ]，hun[x uən]。
In fact,the finals iu,ui and un are the abbreviations of iou,uei,uen, so they have to be pronounced as[iəʊ],[uəɪ] and [uən]. For example: niu[n iəʊ],sui[s uəɪ],hun[x uən].
The rules of writing
4.ɑ、o、e开头的音，连在其他字音后面时，要用隔音符号（’）隔开；如“西安”xi’an。
Between two syllables in which the last one is beginning with ɑ, o or e,there must be a sound insulation symbol(’), otherwise they will be taken as one syllable. For example: “西安” xi’ ɑn(a city name)≠ xiɑn
5.i开头的拼音，后面如果还有别的韵母符号，i要改写成y，例如iɑo→yɑo；如果后面没有别的韵母符号，就在i前加y，例如i→yi。
If a syllable has no initial and the first final is i ,the i should be written into y, such as iɑo→yɑo；If the syllable has no final but the i ,it should be added a y in front of the i when we write the syllable, such as i→yi.
6. u开头的拼音，后面如果还有别的韵母符号，u要改写成w，例如uan→wan；如果后面没有别的韵母符号，就在u前加w，例如u→wu。
If a syllable has no initial and the first final is u ,the u should be written into w, such as uɑn→wɑn；If the syllable has no final but the u ,it should be added a w in front of the u when we write the syllable, such as u→wu.
7. ü开头的拼音，都要在前面加y，同时将ü写作u，如：üɑn → yuɑn , ü→yu。
If a syllable has no initial and the first final is ü ,we should add a y in front of the &u
