Combination pinyin consonant and vowel(3)

Well, like i said before the rest for the combination always same. But there are several special pinyin that we can't combine it just like 'f' + 'i' the result is unknown. Then i'd like to tell that several special pinyin which we can combine and can't combine.

We can't combine :

'b','d','p','m','f','t','g','k','h','zh','ch','sh','r','z','c','s' with 'ü' because there's no meaning when we combine it and there's no sound that can be build with that combination

'f','g','k','h' can't combine with 'i'

And we can combine consonant and vowel but the sound looks different

'zh' + 'i' = cee(make our tongue up almost attach with our mouth cavity, and when we said that pinyin still your tongue up of our mouth cavity)

'ch' + 'i' = chee(make our tongue up almost attach with our mouth cavity, and when we said that pinyin still your tongue up of our mouth cavity and do not forget when you say that there's a wind come out from our mouth)

'sh' + 'i' = shee(make our tongue up almost attach with our mouth cavity, and when we said that pinyin still your tongue up of our mouth cavity)

'r' + 'i' = ree(make our tongue up almost attach with our mouth cavity, and when we said that pinyin still your tongue up of our mouth cavity)


'zh' + 'e' = cee(make our tongue up almost attach with our mouth cavity, and when we said that pinyin our tongue already not in above of our mouth cavity)

'ch' + 'e' = chee(make our tongue up almost attach with our mouth cavity, and when we said that pinyin our tongue already not in above of our mouth cavity and do not forget when you say that there's a wind come out from our mouth)

'sh' + 'e' = shee(make our tongue up almost attach with our mouth cavity, and when we said that pinyin our tongue already not in above of our mouth cavity)

'r' + 'e' = ree(make our tongue up almost attach with our mouth cavity, and when we said that pinyin our tongue already not in above of our mouth cavity)

And i think the hardest part for learning Chinese mandarin is how to make it different to spell 'zh' + 'ch' + 'sh' + 'r' when we combine with 'i' or 'e'. It just needs time to spell that combination correctly
