Do you want me to correct your mistakes, the post is nearly perfect but there are some little mistakes :D

Your Vietnmamese is really good, Which reasons bring you to learn Vietnamese?

Anyways, about your discussion, I feel car sick when I'm in backseat of a car, so I don't choose car as a vehicle to travel. I have been travel by train several time, but actually I don't have much opportunities to look outside the window. The train road usually were built in some remote area, where around it is forest or some short hill mountains. If I had a change to choose, I would like to travel by bicycle : ))

Toi học tiếng Việt khoảng hai năm rồi.

Ban hoc tieng Viet Nam bao lau roi ?

Đi du lịch bằng phương tiện gì tôi cũng thích, miễn là được đi du lịch :)
Bạn đã bao giờ đi du lịch bằng xe máy chưa? Ở Việt Nam rất phổ biến, tôi thì thấy hơi nguy hiểm.
Tôi thích tiếng Ý :) Nếu bạn có thể dạy tôi thì tốt quá. 

Hey Megumi, How are you?

Wow, It's been a long time , about 4 years, I haven't been writing any thing in my language :)) It sounds wierd but, well, It is true. Sometimes I talk with my parents through skype, but for writing somethings, It have been really really a long time :)) But anyways, you are trying to learn Vietnamese, so I think it'd better to write for you in Vietnamese.

First of all, your Vietnamese is nearly perfect, I could understand all of your note :) You just need to refine a little in the sentence struture then everything will be clearly.
I was suprised when you could speak a lot of different eastern languages, You must have a strong love with those languages.
For me, Russian is much much more difficult than English. Eventhough I have been learning Russian for almost 4 years, but I think I could speak in English better.
Why can you learn Chinese, Vietnamse but you couldn't learn Russian. I think Chinese is more different with your language than Russian.

I'm happy when knowing someone out there is studying my language. Yes, you were right when saying that sudying a language help us know more about culture. The best way to know about one country is learn its language :) I hope some day you could speak Vietnamese like a native. Good luck!
