Aerial photo taken on Aug. 16, 2019 shows the historical site of the Yunnan Military Academy in Kunming, southwest China's Yunnan Province. As the provincial capital of Yunnan, Kunming is not only a transport and information hub, but also a regional center for political, economic, cultural, educational, scientific research and social services affairs. The city's mild climates allow fresh flowers and lush greens to grow all year round, making it a pleasant place to visit and live in. (Xinhua/Zhang Xiaoyu)
