The ancient Viet people settled at the junction of the two rivers . At that time, the wet rice civilization was established

The Mekong River Delta, or Southern Delta
This region is approximately 40,000 sq. km. The land is very fertile and has favorable climate conditions for agriculture. As a result, it is the largest rice growing region in Vietnam.

Vietnam is crisscrossed by thousands of streams and rivers. There is a river discharging every 20 kilometers along Vietnam's coastline. The waterways are a very convenient means of transport with major rivers like the Red River in the north and the Mekong River in the south.
Vietnam's coastline is 3,260 km long. If you have a chance to travel along the coast of Vietnam, you will be able to enjoy the beautiful beaches of Tra Co, Sam Son, Lang Co, Non Nuoc, Nha Trang, Vung Tau, and Ha Tien. In some places, you will see mountains jutting out to the sea. One such magnificent site is Halong Bay, which has recently been two times listed as a World Heritage Site by UNESCO.
Vietnam's coast has been awarded a series of large seaports, such as the ones at Haiphong, Danang, Qui Nhon, Cam Ranh, Vung Tau, and Saigon. There are thousands of islands and islets scattered offshore from North to South. Among the most popular tourist destinations are the Truong Sa and Hoang Sa Archipelagos.

The forests of Vietnam account for most of the total land area. National parks are preserved by the state and follow a steady development plan. Some of the more famous national parks located throughout the country include Ba Vi in Ha Tay, Cat Ba in Haiphong, Cuc Phuong in Ninh Binh, Bach Ma in Hue, and Cat Tien in Dong Nai.
Vietnam has a variety of mineral resources. Beneath the forests are valuable minerals such as tin, zinc, silver, gold, antimony, precious stones, and coal. Vietnam also has large deposits of oil and gas on its offshore islands and on the mainland.
Vietnam also has abundant subterranean mineral water sources. These are found at Quang Hanh in Quang Ninh, Hoi Van in Binh Dinh, Vinh Hao in Binh Thuan, Duc My in Nha Trang, Kim Boi in Hoa Binh, and Binh Chau in Vung Tau.

Rivers
The Red River in the north and the Mekong River in the south are the two major freshwater streams. The Red flows almost directly southeast from the northwestern highlands, whereas the Mekong follows an irregular path from Cambodia, crosses southernmost Viet Nam, and empties in the South China Sea through a complex network of distributaries. Both rivers have been leveed to prevent flood damage.

Climate
Vietnam is located in both a tropical and a temperate zone. It is characterized by strong monsoon influences, but has a considerable amount of sun, a high rate of rainfall, and high humidity. Regions located near the tropics and in the mountainous regions are endowed with a temperate climate.
The annual average temperature ranges from 22ºC to 27ºC. In Hanoi, the average temperature is 23ºC, in Ho Chi Minh City it is 26ºC, and in Hue it is 25ºC.
There are two distinguishable seasons. The cold season occurs from November to April and the hot season from May to October. The difference in temperature between the two seasons in southern Vietnam is almost unnoticeable, averaging 3ºC. The most noticeable variations are found in the northern provinces where differences of 12ºC have been observed. There are essentially four distinct seasons, which are most evident in the northern provinces.

Vegetation and Animal Life
Abundant vegetation exists throughout Viet Nam except where the landscape has been denuded. Typical mixed stands in the rain forests contain a wide variety of pines, broadleaf trees, vines, and bamboos. Dense mangroves bordering the distributaries of the deltas often hinder access to the water's edge. The tropical rain forests are inhabited by large mammals such as elephants, deer, bears, tigers, and leopards. Smaller animals, including monkeys, hares, squirrels, and otters, are found throughout the country. Reptiles such as crocodiles, snakes, and lizards, as well as many species of birds, are also indigenous.

Mineral Resources
The northern highlands of Viet Nam contain valuable minerals, including iron, anthracite coal, phosphate, zinc, chromite, tin, and apatite. Petroleum and natural gas deposits lie offshore.

Languages
Vietnamese, the official language, is spoken by the majority of the population (see Austro-Asiatic Languages). The use of French, a remnant of colonial times, is declining. Some Vietnamese people who live in urban areas speak other languages, such as English and Russian. Khmer, Montagnard, and Cham are spoken primarily in the interior.

Currency
The currency of Vietnam is the dong (VND). Notes are available in paper denominations of 500,000; 100,000; 50,000; 20,000, 10,000, 5,000, 1,000, 500, 200 and 100 VND, and also in metal denomination of 5,000; 2,000; 1,000; 500; 200d
