Highest-grossing documentary revels in recent developments

Amazing China, a 90-minute documentary, has become the country's highest-grossing factual movie.

Featuring a number of spectacular aerial shots, the movie - edited down from 1,000-plus hours of footage in seven months - records major developments since the 18th National Congress of the Communist Party of China in 2012.

Mind-blowing sequences include megaprojects, ranging from the Five-hundred-meter Aperture Spherical Telescope, the world's largest radio telescope, to Blue Whale 2, the largest maritime drilling rig on the planet, and the world's longest bullet-train network.
