In Vietnam there are a lot of traffic problems in my country. First, there are too many people using the roads in the rush hour. Second, there are too many vehicles on the road that leads to traffic jams. Another problem is that many roads are narrow and bumpy. Fourth, there are traffic accidents every day so a lot of people are injured. I think we should obey the traffic rules and traffic signs as well.

In many festivals I have attended recently I like Tulip flower festival in Holand best.Last year I and my family went to Holand and took part in Tulip flower festival.It was about 5000 people attended the festival.There were many kinds of flowers with many many colours on the road and in front of the houses.In the morning we bought a lots of flowers in the market.Then in the afternoon we ate in the hotel,the food was delicious.In the evening we watched the colourful parades on the street,the music was great and the dancers sang and danced very well.I felt happy so much.I will remember this festival forever.If I had a chance,I wish I would visit Holand again!
