In Viet Nam festivals often take place during the three months in spring and in autumn when people have a lot of leisure time. In addition, the climate in spring and autumn is especially suitable for holding festivals and for festivals goers to enjoy.
Traditional festivals constitute a form of cultural activities, a spiritual product which the people have created and developed during the course of history. From generation to generation, the Vietnamese people preserve the fine tradition of "remembering the source while drinking water." Festivals are events which represent this tradition of the community as well as honor the holy figures named as "gods" -the real persons in national history or legendary persons. The images of gods converge the noble characteristics of mankind. They are national heroes who fought against foreign invaders, reclaimed new lands, treated people, fought against natural calamities, or those legendary characters who affect the earthly life.
Accordingly, first and foremost, festivals are events when people pay tribute to divinities that rendered merits to the community and the nation. These are occasions when people come back to either their natural or national roots, which form a sacred part in their mind. Furthermore, festivals represent the strength of the commune or village, the local region or even the whole nation. Worshipping the same god, the people unite in solidarity to overcome difficulties, striving for a happy and wealthy life.
Moreover, festivals display the demand for creativity and enjoyment of spiritual and material cultural values of all social strata. Festivals become a form of education under which fine traditional moral values can be handed from one generation to the next in a unique way of combining spiritual characters with competition and entertainment games.
Festivals are also the time people can express their sadness and worries in a wish that gods might bestow favor on them to help them strive for a better life.

Leonardo da Vinci was born on April 15, 1452 in Vinci, Italy. He was the illegitimate son of Ser Piero, a Florentine notary and landlord, but lived on the estate and was treated as an illegitimate son.
In 1483, Leonardo da Vinci drew the first model of helicopter. It did not look very much like our modern day "copter," but the idea of what it could do was about the same. Leonardo was an artist and sculptor. He was very interested in motion and movement and tried to show it in his art. In order to show movement, he found it helpful to study the way things moved.
One subject he liked to study was birds and how they flew. He spent many hours watching the birds and examining the structure of their wings. He noticed how they cupped air with their wings and how the feathers helped hold the air. Through these studies, Leonardo began to understand how birds were able to fly
Like many other men, Leonardo began to dream of the day when people would be able to fly. He designed a machine that used all the things he had learned about flight, and thus became the first model of a helicopter.
Poor Leonardo had only one problem, however. He had no way to give the necessary speed to his invention. You see, motors had not yet been invented and speed was an important part of the flying process. It would be another four hundred years before the engine was invented and another fifty years before it was put to the test in an airplane.
Leonardo's dream of a helicopter finally came to pass in 1936. The Italian painter, sculptor, architect, engineer, and scientist, Leonardo died on May 2, 1519, and was buried in the cloister of San Fiorentino in Amboise.
