The Mekong River is one of the most impressive in South East Asia, flowing through several countries: China to Myanmar, Laos to Thailand, then Cambodia before ending its journey in Vietnam. Its name is of Lao and Thai origin and has been a trade route for centuries, although its flows change greatly from season to season. You can see the fresh water pink dolphin (although quite rare now), a softshell turtle, crocodiles and wave to the many different peoples living along the banks, but what I loved the most were the number of people who lived on the river itself. The trade was as it has been for centuries and the superstitions continued, such as putting eyes on the boat to prevent bad spirits.
Note: These pictures are so old they were taken with film: Christmas 1998.Source: http://en.wikipedia.org/wiki/Mekong
