TV presenter Gok Wan is usually known for fashion and beauty shows, but he branches out into economics in this documentary.
Gok travels through China to see the huge factories that produce one in every four manufactured objects on the planet, from toothbrushes to black cabs.
His visit takes him from his father’s village to vast towns dedicated to producing single products, such as Xintang which makes 260 million pair of jeans every year.
