pinyin consonant(3)

As i told before, Chinese pinyin zh,ch,sh,r are more difficult than other pinyin. Now i'll try to explain what's the different pinyin zh,ch,sh,r with pinyin z,c,s. pinyin z,c,s is just like derivative of pinyin zh,ch,sh,r
The differences is when we try to speak it out the tone, it seems lighter.

I'll give it the explanation, here it is the last of Chinese pinyin

'z' we read "ce"(it seems not different with "zh" but when we try to speak it out it's lighter than "zh", our upper teeth and lower teeth attach just we have a big smile and show our teeth, and our tongue attach with lower teeth)

for me i think it's more simple than i try to speak "zh"

'c' we read"che"(it seems not different with "ch" but when we try to speak it out it's lighter than "ch", our upper teeth and lower teeth attach just we have a big smile and show our teeth, and our tongue attach with lower teeth, but remember when we try to speak that pinyin there's a wind blow out from our mouth)

's' we read "se"(just like "sh" but it's lighter than we speak "sh", the explanation itself it's not different with "c" or "z" but maybe i think when we speak it out there's also a wind blow out from our mouth but not too strong as we speak "c")

And of course pinyin zh,ch,sh,r and z,c,d are more difficult to learn it. It needs time to make it fluent, if i have a mistake about teaching Chinese pinyin you can give me a comment, and i will try to fix it as i can..
