HONG KONG: "Tung Chung River on North Lantau. On the mountain behind there are many Buddhist monasteries that are still in use today. They came here because it's a very remote quiet location. The only access is by foot. There used to be mountains like this all over China but they were mostly abandoned after the revolution. This is the only place I know where there are many that are still active." - CNN's Brad Olson, August 19. Follow Brad (@cnnbrad) and other CNNers along on Instagram at instagram.com/cnn.
