S1, E3: China is a nation of contrasts, and nowhere is it more evident than along its dynamic coastline. This aerial journey takes us from the north’s icy Chagan Lake to the tropical Hainan province’s southern volcanoes, and from the nation’s most populated cities in the east to an abandoned fishermen’s village off Shanghai’s coast. It’s a spectacular voyage highlighting the country’s diverse environments, evolving cultures, and growing prosperity.
