Zhou Lingzhao
On 1 October 1949, Zhou Lingzhao was ordered to paint the portrait of Mao Zedong at Tiananmen Square for the proclamation of the People's Republic of China. In the early days of the founding of the People's Republic of China, he successively contributed to the design of the flag of the Communist Youth League of China (1950), the flag of the Young Pioneers of China (designed by Liu Yiyan in 1950 and modified by Zhou Lingzhao), and contributed to the National Emblem of the People's Republic of China (1950).
