Aerial photo taken on April 25, 2020 shows the interior of a capsule-shaped bulk cargo warehouse in Yueyang, central China's Hunan Province. The warehouse, which is 470 meters long, 110 meters wide and 46.5 meters high, was officially put into use Saturday at Chenglingji Port which locates along the Yangtze River in Yueyang. Its totally-enclosed feature can effectively avoid the dust pollution previously occurring at the port's freight yard, becoming more beneficial to the eco-environment along the river.
