Ho Chi Minh City is a city in southern Vietnam. It is known for its French colonial landmarks, including Notre-Dame Cathedral, made entirely of materials imported from France, and the 19th-century Central Post Office. Food stalls line the city's streets, especially around bustling Bến Thành Market. The Mekong Delta, the region where the Mekong River empties into the South China Sea, is a maze of rivers, swamps, and islands home to floating markets, Khmer pagodas, and villages surrounded by rice paddies.
