Aerial photo taken on Aug. 31, 2017 shows buildings on the Gulangyu island, southeast China's Fujian Province. Located on the southeastern coast of China, Fujian Province is lying between mountains and the sea. Acting on the understanding that lucid waters and lush mountains are invaluable assets, Fujian in recent years has achieved great successes in terms of ecological development. The province has ranked China's No. 1 for 40 years with a forest coverage rate passing 67 percent. Besides high water quality, local residents also enjoy good air quality on over 95 percent of days in main cities of Fujian. Benefiting from its natural environment, Fujian keeps pioneering sustainable economy, mechanism invigoration, sound livability and good life. On June 13-15, the Beijing International Horticultural Exhibition exposes visitors to Fujian's sound livability and natural beauties with a Fujian Day theme event. (Xinhua/Zhang Guojun)
