Oh!I`m sorry for I make a big mistake ,because in HK,many people call putonghua.Do you mind I ask you where are you come from??
Thanks for you add the pinyin <--I don`t know am I right or not[/quote]

It's not really a big mistake. Linguists and people who study the Chinese language will sometimes use the term 'putonghua' as well. It is just less common among English-speaking people who are not as familiar with Chinese.

I am from the US. ^^ But I'm Taiwanese. And you're welcome. I didn't learn pinyin until recently, since Taiwanese use a different phonetic system.[/quote]
Really?!I love Taiwan and there is not use pinyin...
Is this:
ㄅ=B ㄆ=P ㄇ=M ㄈ=F
I ike it,it`s so interesting and so smart
