Five years ago, I attended a very big festival in Ha Noi. It’s called 1000th Anniversary of Thang Long – Ha Noi Festival. There are a lot of activities in this festival such as fireworks display, military parade, music performances, ect. It was organized very splendidly because the organizers are the Viet Nam government. Millions of people came to Ha Noi to participate in this great festival. It was held for ten days from October 1st 2015 to October 10th 2015. I saw lots of fireworks, parties, parades during these days. It was interesting. I took so many pictures on this festival because there were plenty of beautiful scenes. We organized this great festival to celebrate the 1000th anniversary of Thang Long – Ha Noi.
