What do you think Mao meant when he called on students to root out the poisonous weeds in the schools?

When Mao called on students to "root out the poisonous weeds" in schools, he was urging them to identify and eliminate perceived counter-revolutionary elements and traditional values that contradicted Communist ideology. This rhetoric reflected the broader Cultural Revolution's goal of purging society, including educational institutions, of influences deemed harmful to the revolutionary spirit. By framing dissenting ideas as "weeds," Mao aimed to mobilize youth as active participants in reinforcing ideological purity and loyalty to the Communist Party.
