The Mid-Autumn Festival is an important traditional holiday in my country. Mid-Autumn festival is celebrated not only in Vietnam but also in some other parts of Asia as well, such as China, Japan or Korea. And it is often celebrated on the 15th day of the 8th month of the lunar calendar with full moon at night. In the past, on this day the moon was brightest and roundest which represented the family reunion or gatherings. Therefore, families and friends often came together or harvested crops for the festival. Nowadays, Mid Autumn Festival is mainly for young children in Vietnam to enjoy the best time of the year. But not only can children celebrate this day but also adults can, adults who wish to have a chance to remind their their childhood and feel young again.
Hello everyone, my name is Nii. Today, I would like to tell you about Tet, also known as the Lunar New Year festival, which is the biggest traditional festival in Viet Nam. It takes place from the first day of the first month of the lunar calendar until at least the third day.

There are many special food is made so as to prepare for Tet meal such as sticky square cake, Vietnamese sausage, sticky rice, and jam. The food is thought to reflect Vietnam’s habits and customs as well as Vietnamese’s lifestyle. Besides, the meal has other dishes like fish, vegetables to show the hope for a successful and prosperous new year. In terms of customs, children’s receiving red envelop from the elder, visiting relative’s houses, and going to church are popular activities. Giving lucky money is thought to bring children hope and health. Church is the symbol of peace; therefore, individuals go there and pray for a successive year. Traditionally, the house is designed with peach flower in the North and Ochna integerrima in the south part of Vietnam. Besides, the house as well as the town are clear, decorative, and beautiful as all are ready to start a new year. People have a cozy atmosphere and enjoy a joyful time with their family members. It’s high time for people living in different parts of the country to gather and spending time together. Tet is a chance for one to come back home after many stress and pressure of studying and working environment. Tet is not simply a holiday, it is a culture and habit of Vietnamese since its deep meaning is sacred and important. All in all, Tet includes not only joy but also a long-standing event in people’s souls as it helps one grow up through experience. And that's all about the Lunar New Year festival in Vietnam.
