日食的发生由于和帝王的“失德”、朝廷的“失政”联系起来,因而对唐五代帝王的行为有所规范和约束,进而成为制约皇权膨胀的无形力量。皇帝和执政大臣不得不从儒家倡导的“修德”和“修政”观念中寻求禳除灾祸的措施,通过大赦、改元等方式广施仁政,勤修政事,对当前的社会问题给予关注和解决;另一方面,日食的出现使得唐五代朝廷定期举行的朔日朝会被迫取消或中止。而与之相反的是,“合朔伐鼓”的救日礼仪却被凸现出来。 The occurrence of solar eclipses is linked with the “dislocation” of the imperial court and the “lost government” of the imperial court. Therefore, the behavior of the emperors of the Tang and the Five Dynasties is regulated and restrained, and then becomes an invisible force that restricts the expansion of imperial power. The emperor and the minister of state had to seek measures to eliminate calamities from the concepts of “revisionism” and “revision of the government” advocated by the Confucianists. They should pay attention to the current social issues by means of amnesty and reform, On the other hand, the appearance of eclipse causes the Shu-Rien-Chao, which is held regularly by the court of Tang and Five Dynasties, to be canceled or suspended. On the contrary, the salvation of the Sabbath day was highlighted.
