Roofs of residential buildings, office buildings and school buildings turn green in this aerial photo taken May 5, 2019, in Zhengzhou, Central China's Henan province. A greening project has covered 90,000 square meters of roofs with sedum lineare, a plant that is resistant to cold, draught and heat. The greening project can extend the life of a building by protecting roofs from sunshine and rainfall. [Photo/IC]
