Because there is a solar eclipse, this is an ominous sign. The emperor and his ministers couldn't watch the people suffer disasters and the country was destroyed, so they came up with various remedies in order to reverse the heavenly heart. The emperor should think of Xiu De, and ministers should carry out rescue activities. The rescue method recorded in Yi Si Zhan is as follows: When there is a solar eclipse, the Emperor wears plain clothes and takes refuge in the temple, and martial law is strictly enforced inside and outside. Royal astronomical officials closely monitor the changes of the sun at the observatory. When they saw the solar eclipse, they beat the drums to drive Yin Qi away. Ministers who heard the drums all wore red headscarves and held swords to help the sun be the spirit and restore light to the sun. Some more enlightened emperors also sent themselves a letter, indicating that they had considered Xiu De.
