A teacher holds up a bowl with red ink for a young girl (a Pioneer) standing on a chair and painting characters on an anti-Lin Biao and Confucius wall poster. The girl is painting the slogan 狠批"克己复礼" - Ruthlessly criticize "restrain yourself and return to the rites" (a quotation from Confucius' Analects). In the background another teacher is assisting pupils putting up anti-Lin Biao and Confucius slogans in the schoolyard.
