Aerial photo taken on Feb. 3, 2019 shows tea farmers picking tea leaves at Zhouya Village of Doujiang Township in Sanjiang Dong Autonomous County, south China's Guangxi Zhuang Autonomous Region. The local spring tea goes on market every year before and after "Lichun", literally meaning the beginning of the spring. Lichun is the first of the 24 solar terms of the Chinese lunisolar calendar, which falls on Feb. 4 this year. (Xinhua/Gong Pukang)
