Mainland Southeast Asia / 中南半岛
Mainland Southeast Asia / 中南半岛 is the regional frame in EP267 踏访湄公河：雨季、婚飞蚁与水利帝国. The episode emphasizes that the peninsula can feel familiar to Chinese travelers through tourism, Buddhism, food, and proximity, while still being difficult to understand because multiple states, ethnic groups, histories, and river systems interlock in a compact area.
The source’s main geographic formula is that the region is shaped by north-south mountains and rivers. This supports Mainland Southeast Asia River-Valley State Formation / 中南半岛河谷国家形成: different valleys and uplands make movement possible in some directions, difficult across others, and politically consequential when groups such as Lao, Thai, Vietnamese, and Khmer communities build states in different ecological corridors.
