Total solar eclipse or total lunar eclipse

"Disasters are different", "The day changes to Xiu De, the moon changes to save the punishment, and the stars change to harmony" (after the eclipse, the morality should be increased, the sentence should be reduced, and the harmony should be paid attention to after the astrology is abnormal). As usual, the monarch should change into plain clothes, stop recreational activities, lower the standard of diet, stay in the wing behind closed doors and even commit crimes, solicit criticism and suggestions from his subjects, and take specific measures such as pardoning criminals and reducing taxes to show his sincerity in repentance. It means the position of the emperor.

Change the dynasty, disaster strikes, or the emperor makes mistakes, which means fierce!
