Original: While some Hmong returned to their villages and attempted to resume life under the new regime , thousands more made the trek across the Mekong River into Thailand , often under attack . This marked the beginning of a mass exodus of Hmong from Laos .
Simplified: Vietnam has 787,600 Hmong people , Laos has 320,000 Hmong people , and Thailand has 150,000 Hmong people .
