Sang was 15 when she left school and, together with a friend, crossed over to Thailand to seek employment.
Sang initially obtained work on a pomelo farm in Thailand and then as a housekeeper, both at low pay. After nine months, Sang became homesick and tried to return home, but was arrested and repatriated back to her family. Within two weeks, a man from another village approached Sang and her friend with the offer of a well-paying job in Thailand. Enticed by the opportunity to improve her circumstances, Sang agreed and was transported overland to Thailand.
