Dear ...(tên)...,

I'm so sorry I haven't written to you in a long time, so today, i'm very exciting to talk to you about my hobby. As you know, English is an important language, so my hobby is learning English. I usually watch English film or listen to English music to improve my skills. My parents always encourage me to study English because most of the big companies now need English. My dad also good at English so my study become easier. All you need is be patient and hard-working! I think all of children should learn English when they were a child. I wish my country will develop. And you? What is your hobby? Looking forward to hearing from you!

Your friend,

Dear Khang

I am well here and hoping the same for you. Last week you dropped me a letter in which you asked me about my hobby.

My hobby is making models of aircraft. Aero-modeling is an interesting hobby to me because when you think over new techniques during modeling, your mind is pushed towards the creative work and new ideas are developed. Aero-modeling can also be a paying hobby. We can send some of our best models for competition and not only get prizes but also get a good name. Now I will finish my letter. Give my regards to your parents.
