The Mekong River is the lifeblood of Southeast Asia, flowing through six countries and providing crucial resources for millions of people. There are several synonyms for this mighty river: the Lancang River in China, where it originates; the Mae Nam Khong in Thailand, meaning "Mother of Water"; the Tonle Thom or "Great River" in Cambodia; and the Song Cuu Long or "Nine Dragons River" in Vietnam, referring to the nine tributaries that merge to form the Mekong Delta. These different names reflect the rich cultural heritage of the region and the significance of the river to the people who live along its banks.
