This is a letter I wrote my friend. Could you please help me correct the grammar. Thanks so much..
Every time getting your reply, I'm very delighted.
Have you already got through the exam ? How was you doing ? it was good ? I hope so. Now, I also prepare the final exam before having the Lunar New Year. Everything gradually makes me get busy.Ah, to tell you about this, I've just decided to retake part in "W&T' again. This time, I hope I will make a great trip in the US. And I have much time to prepare for it, not like the previous trip, nothing was prepared

It's great. But I still don't know where I will set foot, I want to discover another state.
About my country, hehe. First of all, I'm really suprised at the age of getting married in your country because, in my country, people get married at about 27 or 28. That usually happens in the city. But in many countrysides, ones get married so soon that it's incredible. Try guessing !!! That's.......17 or 18 years old for women maybe less than, oh my god ! That is also a problem my government need to have methods to improve this one. In compensation, people who live in the countryside have much great virtue than others; for instance, their honesty. I appreciate love them about this. I love the climate, the scenery, and people... there

How about you, in your country ? One more thing that Vietnamese are very hospitable, this will be proved when you visit VietNam, haha. It's true that we are happy when foreigner can speak vietnamese. I think it's the same as your country, is that it ?
I usually go online in my free time, almost everyday, to read the news, to listen to music, to learn english... As you said, you've joined yoga club, I've also join a kung-fu club, karate, in the evening, hehe. Quite tired but great. Which kung-fu is popular in ur country ? Taekwondo, Karate, Judo and Vovinam (vietnamese kung-fu) is the most popular in my country.
Have you ever tried practising the kung fu ? If so, which one ?
I look forward to your reply.
Best wishes,
