I don't know much about the art of contemporary China.
I know that there are a lot of political posters featuring Mao.
And I know from a biography of Wu GuanZhong that he and other artists were "reformed through labour".
Reading here: http://chineseposters.net/gallery/ Then am I beginning to understand that the political posters communicate not an ideology, but different ideologies - it's a media that was used by different parties, including both the democrats and the communists - to communicate their message to the masses.
"The bulk of China is controlled by the Nationalist Party (Guomindang, 国民党, old transcription: Kuomintang), which is especially strong in the urban areas. The Communists entrench themselves in the countryside. Both parties use posters to try and mobilize the population to resist the common enemy, Japan."
Here are some examples of earlier posters not featuring Mao.
