bie  ting tamen zhuang B(It means "show off") ni shuo de hen hao, mei shen me xu yao jiu zheng de~

But~u just had point:zìxué  The pronunciation of this word like "ZOO SHIT" (It's funny)

:)

Wǒ de míng zì shì defane , he wǒ  zì xué de zhōng wén.

1) If you want to say "My name is Defane and i am learning Chinese myself." You can use "," to take the place of "he(和)"..In Chinese,"he（和）" is often used between 2 nouns.For example:我和你,桌子和椅子。

2)I personal advise you to write characters instead of Pingyin.And the characters of  that should be "我的名字是Defane,我自学中文"。In China,we always use characters ;).If may be a little hard for you to use characters at first,but it is really helpful for you to learn Chinese ;)

I hope it helps,and if you have trouble learning chinese，feel free to ask me ;) Good lluck with your study ;)
