Yang Liu (L) tutors Yang Jinyi, the only student of Yanggu Primary School in Dabaidi Township of Ruijin City, east China's Jiangxi Province, on May 7, 2019. Ruijin is recognized as the "red capital" and a cradle of the Chinese revolution because the forerunner of the People's Republic of China, the Provisional Central Government of the Chinese Soviet Republic, was founded there in 1931. In July 2018, Ruijin announced that it had successfully cast off poverty. (Xinhua/Lan Hongguang)
