Nghe An Province: Unveiling Vietnam's Harsh Reality and Human Trafficking Hub

There's a saying in Vietnam about the Nghe An province: "Chó ăn đá, gà ăn sỏi."

It means "the dogs eat rocks, the chickens eat pebbles".

It's a hot, tough place to live, and is also Vietnam's hub for the trade in human cargo.

When 39 Vietnamese were found dead in a lorry in Essex four years ago, the majority had left from Nghe An.
