Vietnam is one of the most beautiful countries located in the South East Asia. In the North, Vietnam shares the long borderline with China. In the East, Vietnam is bordered by the Gulf of Tonkin, inn the East and South by the South China Sea, in the South West by the Gulf of Thailand, and in the West by Cambodia and Laos. Owning to stretching the length of the Indochinese Peninsula, Vietnam boasts a unique shape of an elongated S and a long coastline of 3,260km with a lot of wonderful sites.
Although Vietnam lies entirely within the tropics, the Vietnam’s climate surprisingly varies from region to region with the annual average temperature from 22ºC to 27ºC because of its topography. The mountainous people of Sapa in the north might be seeking shelter from snow while the urban dwellers of Ho Chi Minh City in the south seek refuge from mid-day heat.
In the North (from Hai Van mountain pass in the middle of Vietnam to the North), it is the weather of four different seasons in a year: Spring, Summer, Autumn, and Winter. Spring lasts from February to April with warm weather. In Spring, it is characterized by fine drizzle that helps plants grow fast and flowers bloom brightly. Summer lasts from May to August with hot and showery weather. The sun shines almost days. And there are sometimes sudden thundershowers that make summer less hot and become cooler. Autumn lasts from September to November with cool air, and dry and lightly windy weather. It can be said that it is the most beautiful season in a year with yellow leaves falling on the streets and yellow bright shines in day time although sometimes typhoons threaten life and agriculture in the country. Winter lasts from November to January with cold and dry weather. It is the coldest season in a year. Frost and snow can also occur in the mountains (over 1000m above level sea), that make Vietnamese people eager to go up to see and take nice photos of such scare event of a year.
The southern region is predominantly sub-equatorial with two main seasons of wet rainy season and dry season. A wet rainy season ranges from April to September. It is often sunny in mornings and rainy in late afternoons. Showers often rain heavily but stop quickly. A dry season spans the months of October to May. The weather becomes hotter. The Sun shines all days. But it becomes so cool at night. Definitely, the weather is rather stable in the south.
The official language of Vietnam is Vietnamese, which is the mother tongue of the Vietnamese people who constitute 86% of Vietnam's population, and of about three million overseas Vietnamese. And it is the second language of the ethnic minority groups in the country. It is monosyllabic, with each syllable having six different tones that can change the meaning of the word. This makes it quite difficult for new learners. Beside the official language, each ethnic minority group has its own dialect that has been used and preserved in daily life.
The Vietnamese writing system in use today is an adapted version of the Latin alphabet, with additional diacritics for tones and certain letters. The different tones are indicated by the use of accent marks. This system of writing, called quoc ngu, was created by a French Catholic missionary, Fr. Alexander De Rhodes, in the 17th century to translate the scriptures. When France invaded Vietnam in the late 19th century, French gradually replaced Chinese as the official language in education and government. Vietnamese adopted many French terms, such as đầm (dame, from madame), ga (train station, from gare), sơ mi (shirt, from chemise), and búp bê (doll, from poupée). In addition, many Sino-Vietnamese terms were devised for Western ideas imported through the French. However, the Romanized script did not come to predominate until the beginning of the 20th century, when education became widespread and a simpler writing system was found more expedient for teaching and communication with the general population.
