It's a staple of Chinese cuisine and a symbol of purity and perfection in China. Lotus root is now being exported across the globe. Filled with vitamins and minerals, it's a popular ingredient in Chinese cuisine. With its neutral taste, it can be used in desserts or savoury dishes. We go behind the picture postcard beauty of the Lotus flower to see how the roots end up on our plates. But first we head to Burma, where Muslims from the Rohingya ethnic group continue to flee to Bangladesh. The Rohingya are considered by the UN to be the world's most persecuted minority. The current army offensive against the Rohingya has alarmed the UN and human rights groups, who warn of crimes against humanity and even genocide.

We also go to Afghanistan, where many young children are heading out to work instead of going to school. Many youngsters work on dangerous mountain roads, directing traffic in exchange for tips, in order to help their families make ends meet.
