Abstract: This article examines the seventh and eighth chapters Chunqiu Zhengci ( Commentary on The Spring and Autumn Annals) by Zhuang Cunyu，and highlights its main ideas on criticizing regicide and restoring the king order of The Spring and Autumn Annals. Comparing those two chapters with previous and the Qing official commentary books，we can find that no matter whether he followed or deviated the official viewpoints，Zhuang Cunyu never changed his perspectives of defensing the king order. Zhuang Cunyu accepted and went even further than the official viewpoints which took The Spring and Autumn Annals as domination rules of admiring the king and defensing unification. Being an official in charge of culture and education in the Qianlong reign，Zhuang Cunyu’s sticking to the official viewpoints should be interpreted not only with his core cares，but also with his family background，experiences，character，and many other factors.
