Dear Mary,

It has been a month since my last letter. How are you? Do you enjoy your trip to London? So today, I'll talk to you about my fascinating trip this summer. I and my family went to Hanoi. This is the second time we've been here. The weather was hot. I did a lot of things. First, we went to Hoan Kiem Lake. It was so beautiful and I love it! After that, we went to West Lake and had some traditional dish here-"Banh tom". It's delicious! Then, we visited the Ho Chi Minh mausoleum. It is very large and surrounded by trees and flowers. Finally, I rode a bike around Hoan Kiem Lake with my parents and walked around the Old Quarter at night! It was fun! 

So how about you? Tell me about your trip! Looking forward to seeing you.

Love, 

Nga

Dear Mary,

How are you? Thank you for your wonderful gift. I think you got an enjoyable summer holiday. And I would like to tell you about my last summer holiday.
I spent my summer holiday with my family in Da Nang for 3 days. These were really great days for me. On the first day, we had a trip to Ba Na Hills. The atmosphere was very fresh,and  it made me feel good. We visited many places such as Fantasy Park, Debay Cellar, French Village.
On the second day, we went to visit My Son Sanctuary and went swimming in the afternoon. Da Nang beach is very pure and the scene is really beautiful. So I took many nice pictures.
And on the last day, we just walked around the town, and enjoyed  some delicious dishes of Da Nang such as bun Quang, banh trang thit heo, etc and bought some souvenirs. I have a great gift for you. I will send your gift and the beautiful pictures that I took for you.

I really had a great time with my family. Da Nang is a wonderful place and people in here are friendly. I think this is a place I shall never forget. So how is your summer vacation? Write to me and tell me about it.
I'm looking forward to hearing from you soon.
Love,

Nga
