Dear grandpa and grandma,
Da Lat City is great! Its weather is cool during the  day. The people here are incredibly friendly and kind. Da Lat’s food is delicious. Our hotel is modern. It has a swimming pool, so every morning I ofent swim  in it. Yesterday Mom, Dad and I went to Xuan Huong Lake first. Its landscape is very beautiful. There are many flowers and trees. After that, we visited Langbiang Moutain. I stood on the peak of the Moutain and saw the whole view of the city. Tomorrow, we will go to city's Flower Garden, Love Valley, ect. I like Da Lat city because It’s a fantastic city.
Wish you were here !
Best wishes,

Ha Long Bay is one of the seven natural wonders in the world. It is located in Ha Long city, Quang Ninh province in the north of Vietnam. It is about 200 kilometers from Hanoi to Ha Long city. Therefore you spend 4 hours on travelling there by car. If budget is not a problem, an hour-long helicopter transfer is also available. The ideal season to visit Ha Long Bay is summer when the weather is warm and sunny. There are lots of beautiful caves and islands in Ha Long, so you must take a boat trip and go sightseeing. You can do water sports here like swimming, sailing, and windsurfing. Moreover, the seafood is really fresh and delicious, you must try at least once, especially grilled squid. To sum up, Ha Long Bay is an ideal place to relax after hard-working days.
