Mid-Autumn Festival is under the full moon day of the lunar calendar every year in August, over 4,000 years ago. This is the day children’s festival, also known as the “Festival looks Moon”. Children are expected Tet is because adults are often donated toys, usually light. His star, mask, light pull troops … and pies, cakes plastic. Besides the Tet Holiday, Mid-Autumn festival is one of the most famous festivals and it is a traditional celebration for Vietnamese children.

In this new year, we organized presentation deck, looks moon. Everywhere is fallen in the active and colorful air. Children are provided with many nice lanterns – star lanterns, flower lanterns and diverse funny masks for special performance in the evening of the full moon. In some areas, people also held dragon dance, lion dance to the children happy. The main point of the Mid-Autumn is that children use the beautiful lanterns, wear funny masks, perform fantastic lion dances and sing folklore songs in the house’s grounds or on the streets when the moon is rising.

In Vietnam, Moon cakes are the specific cakes and are only on this festival. Moon cakes, which are made from flavor, dried fruit, meat, egg, pumpkin’s seed, peanut, are so sweet and good tasting. Moon cakes symbolize Luck, Happiness, Health and Wealth on the Mid-Autumn day.

Mid-Autumn celebration is also an opportunity for members of the family to get together and share everything in their year. The young generation express their gratitude to the old generation. The parents show their love for their children. For others, because the traditional time to have this festival is usually after harvesting the crops, it is as the congratulation for the full harvest.

Apart from moon cakes and lanterns, the other most visible tradition related to Mid-Autumn festival is the lion dance. On the nights leading up to the holiday, groups of children parade through the streets – some of the children maintain a martial beat on drums, while others control an extravagantly decorated ‘lion’ crafted from molds and paper.

The children approach homes and businesses and ask the owners for their permission to perform. If they agree, the children put on a show that is believed to bring a blessing of luck and fortune. Afterwards the host gives the children lucky money as a sign of gratitude.

1.Ha Long Bay:

The karst seascape of Halong Bay is one of the world's most spellbinding sea views and is a UNESCO World Heritage Site. Thousands of limestone islands sit within this bay in the Gulf of Tonkin, eroded into jagged pinnacles by wind and water action over millennia. With the bay's scenery best seen by boat, this is prime cruising territory. Opt for at least an overnight tour to see Halong Bay's iconic views as a day trip doesn't do it justice. There are plenty of caves in the bay that can be entered including the Hang Sung Sot, with three mammoth caverns, and the Hang Dao Go, with superbly weird stalagmites and stalactites. For most people though, the highlight is simply cruising amid the karsts and soaking up the changing scenery of pinnacles as you pass by.

I. Talk about one city in your country:

1 - What's the name of the city ?

2 - When did you go there ?

3 - Where is it located ?

4 - How is its landcapes ?

5 - How are the people there ?

=> My area has a beautiful luxury city called ...(replaced by the name you want) , which is to the west of my home village. Because it’s a bit far, about .... kms far from my local town, so I sometimes go there, just when it’s necessary. The last time I’ve been there was 2 months ago to attend an extra English course. Honestly speaking, you will be impressed by its beauty. People there are very friendly and warm-hearted, they’re always ready to help you solve your problems.
