Today I really want to be a bilingual speaker!

Today I met a woman who are working WORKS for A head-hunting company. 

She looks like AN original Chinese woman but she had a talent to express everything both of in Chinese and English.
Especially She was had perfect pronounciation pronunciation and expression to deliver her own meanings.
After the meeting was closed, I can't help BUT envying her ability.
So I decided to continue practicing English everyday.

Notes:

-You can say bilingual in English and Chinese, bilingual, or speak both English and Chinese. "To be a bilingual speaker" sounds a bit vague without saying I am a bilingual speaker of Chinese and English, which may work (*any opinions, English speakers?*)

-are working = you should use the singular, "is working", however, if someone works a job for an extended period of time we would say "works", so who works is best.

-original Chinese = this is not something we say in English, it sounds as though she was changed from Chinese into something else, e.g. French, if you catch my meaning! Instead say looks Chinese, looks like a native Chinese citizen, or something like that.

-Especially = Especially would usually come in a different place in that sentence, like She especially had

- to deliver her own meanings = While this makes sense, it is not a native collocation. We would say She had perfect pronunciation and (an) ability to express herself, she had perfect pronunciation and could express herself clearly/well, or something of that sort. 

-The phrase I can't help in *this case* is followed by a but and a bare infinitive, e.g. I can't help but cry when I see her face, I couldn't help but smile at the song, etc.

Your main issue seems to be finding native ways to express things. While I personally believe sounding native is overrated, especially in regards to pronunciation, it may help to find tried and true expressions that you can re-use in conversations. I often find a cool phrase and use it as often as I can till it becomes part of my permanent vocabulary. Don't be afraid to do that as you expand your vocabulary - it will help until you get an intimate understanding of the grammar of English.

Good work! And as for your determination to be bilingual, that is a great decision. Stick with it and don't give up. Even a basic understanding takes you a long way and help you communicate! A journey of a thousand miles begins with a single step :)
