Answer
The resignation of Hu Yaobang, former General Secretary of the Chinese Communist Party, stemmed from accusations of "laxness" and "bourgeois liberalization" leveled by his political opponents. This primarily referred to his perceived tolerance of diverse ideological viewpoints and intellectual freedom within the party. In essence, he was seen as overly permissive of views outside the orthodox party line, a move deemed undesirable within the highly regimented political landscape of China.
