Da Lat city is located in the center of the southern highlands, 300 km far from the north of Ho Chi Minh City. In this beautiful city, the weather changes constantly, the noon is quite warm and cool while in the evening it is greatly cold. In general, the climate is relatively mild and suitable for avaiable flora and fauna to grow. This is also the reason that in Da Lat there are many kinds of beautiful and precious flower. When we come here , it is that we go to the forest with all kinds of flowers such as hydrangea flowers, mi mo da flowers, Mexican sunflowers, ... In addition, in Da Lat there are many interesting places such as Me Linh coffee garden, Than Tho lake, Camly waterfall, Da Lat station, ... The more we discover, the more beauty and excitement in Dalat we find. I hope that there will be more opportunities to come there in the near future.

But I think Ho Chi Minh City is more beautiful and more expensive than Da Lat City. Because it's the largest city in Vietnam with an extremely huge amount of residents, so almost every street and corner in the center of the city is always bustling. Saigon is famous for its skyscrapers and crowded malls. People love to do shopping, so every weekend the shopping malls are always full of shoppers. The life-style here is very fast and hurried, but people try to spend their free time in the evenings hanging around the streets. Saigon at night is very beautiful, people love to gather in the coffee shops or sit in river banks that go along the streets. My friends and I usually hang out in the evening, and we would to find as many different places to eat as possible. Along with the beauty, Saigon is also famous for delicious fool, and it is felt that the street food is usually better than one in big restaurants. There are so many things left to say about this lovely city, and we can only see the rest of it by exploring it ourselves.
