There were several instances of receiving an appointment and subsequently being demoted. Upon dismissal from his last appointment, he was accused of numerous crimes and a petition was made for his execution. Much of this opposition was headed by Han Tuozhou, the Prime Minister, who was a political rival of Zhu's. Even though his teachings had been severely attacked by establishment figures, almost a thousand brave people attended his funeral. After the death of Han Tuozhou, Zhu's successor Zhen Dexiu, together with Wei Liaoweng, made Zhu's branch of Neo-Confucianism the dominant philosophy at the Song Court.
