I took part in a traditional games festival in my school in HCM City (chỗ này có thể thay thế được). The festival lasted for one day. There were three activities in this festival: water-fetching by hand, tug of war and mandarin square capturing. In the water-fatching by hand contest, three people from each team had to get the water by hand and pour the water into the bottle. In tug of war, ten people from each team have to pull a rope in the opposite direction from the other team. In mandarin square capturing, five people from each team placed one big stone in each of the rice field squares. The first player took up all the pieces of any rice field square on his/her side of the board and distributed one piece per square starting at the next square in either direction. When all five pieces are distributed, the player would repeat again and another player do the same too.The game ended when all the pieces are captured. After the three contests my group won the second prize. The festival was wonderful.

Of course, there are all different kinds of environmental problems and I do not know which problem you want discussed. I will write about global warming.

One of the major environmental problems today is global warming. It is caused by an excess of carbon dioxide in the atmosphere. This causes what is known as a "greenhouse effect."

The major effect of this greenhouse effect is to raise the temperature of the world as a whole. If this continues, climate patterns around the world will change. In addition, sea levels will probably rise, which will be bad for low-lying areas.

There are many possible solutions, all of them have to do with emitting less carbon dioxide -- either by using less energy or by finding energy sources that do not emit carbon dioxide.

Well, to start off, I would like to describe Tet, which is the most crucial national festival of Vietnam. In Vietnamese culture, Tết marks the beginning of the Lunar New Year. It usually lasts three days but celebrations continue for at least the first week of the New Year.
Moving on to the next question, in my opinion, the primary reason for its appearance is that Tết is a special occasion for family reunions as well as for celebrating the arrival of spring.
To celebrate the New Year, we do lots of things together. Before New Year’s Eve, we prepare some local specialties, such as Chưng cake, Vietnamese sausage and dried candied fruits to worship our ancestors and then enjoy during Tet. Houses are thoroughly cleaned out and then nicely furnished in the hopes of getting rid of the past year’s bad lucks. Additionally, many families usually decorate their houses with Kumquat trees, Apricot or Peach blossom and parallel sentences that are believed to bring luckiness, happiness and prosperity to them in the New Year.
All members in a family gather together and have parties to ring in the New Year. During Tết, there are a lot of customs practiced, such as giving lucky money to children, visiting friends’ houses and going to churches, temples or pagodas to make good prays for their family.
If there’s time left, I would like to explain its importance to our culture and me. With Vietnamese, Tết is vital as it’s a very meaningful tradition to welcome the New Year. And it’s more important because Tet is the time for families and relatives to gather under the same roof for rekindling love and bonding. For me, I always long for Tet as it’s the longest holiday, which can help me recover my battery after a long working year.

Vietnam's recorded history stretches back to the mid-to-late 3rd century BCE, when Âu Lạc and Nanyue(Nam Việt in Vietnamese) were established (Nanyue conquered Âu Lạc in 179 BCE).^[1] Pre-historic Vietnam was home to some of the world's earliestcivilizations and societies—making them one of the world's first people who praced agriculture.^{[2][3][better source needed]} The Red Rivervalley formed a natural geographic and economic unit, bounded to the north and west by mountains and jungles, to the east by the sea and to the south by theRed River Delta. According to myth the first Vietnamese state was founded in 2879 BC,^[4][5][6] but archaeological studies suggest development towards chiefdoms during the late Bronze Age Đông Sơn culture.

Vietnam's peculiar geography made it a difficult country to attack, which is why Vietnam under the Hùng kings was for so long an independent and self-contained state. Once Vietnam did succumb to foreign rule, however, it proved unable to escape from it, and for 1,100 years, Vietnam had been successively governed by a series of Chinese dynasties: the Han, Eastern Wu, Jin, Liu Song,Southern Qi, Liang, Sui, Tang, and Southern Han; leading to the loss of native cultural heritage, language, and much of national identity. At certain periods during these 1,100 years, Vietnam was independently governed under the Triệus, Trưng Sisters, Early Lýs, Khúcs and Dương Đình Nghệ—although their triumphs and reigns were temporary.

During the Chinese domination of North Vietnam, several civilizations flourished in what is today central and south Vietnam, parularly the Funanese andCham. The founders and rulers of these governments, however, were not native to Vietnam. From the 10th century onwards, the Vietnamese, emerging in their heartland of the Red River Delta, began to conquer these civilizations.

When Ngô Quyền (King of Vietnam, 939–944) restored sovereign power in the country, the next millennium was advanced by the accomplishments of successive dynasties: Ngôs, Đinhs, Early Lês, Lýs,Trầns, Hồs, Later Trầns, Later Lê, Mạcs, Trịnhs,Nguyễns, Tây Sơn and again Nguyễns. At various points during the imperial dynasties, Vietnam was ravaged and divided by civil wars and witnessed interventions by the Songs, Mongol Yuans, Chams,Mings, Siam, Manchus, French.

The Ming Empire conquered the Red River valley for a while before native Vietnamese regained control and the French Empire reduced Vietnam to a French dependency for nearly a century, followed by an occupation by the Japanese Empire. Polial upheaval and Communist insurrection put an end to the monarchy after World War II, and the country was 

The Vietnamese people from ancient times have many precious traditions preserved and handed down. These traditions are the tradition of fighting the enemy

Many people have fallen for the peace of our lives today. Therefore, we need to study well to build the country more and more beautiful and never forget the gratitude of the previous generation.
