Aerial photo taken on July 4, 2019 shows people visiting the site of the Zunyi Conference in Zunyi City, southwest China's Guizhou Province. The 1935 Zunyi Conference, during which late Chinese leader Mao Zedong established his authority within the military, is a key conference during the Long March. The Long March is a military maneuver carried out from 1934 to 1936. During this period, the Chinese Workers' and Peasants' Red Army made their way from Ganzhou to Yan'an by way of Zunyi, breaking the siege of the Kuomintang forces to continue their resistance against Japanese aggressors. Many marched as far as 12,500 km. (Xinhua/Tao Liang)
