Ancient prose: the interpretation of Uighur

"Ghost Night", also called "Ghost Night", refers to the last night when the soul stays on earth seven days after the death of the deceased. That night, the dead, escorted by the "Yin official", returned to their favorite place before their death. Of course, most of the dead will go back to their homes, but because when they return to evil spirits, that is, when the dead go home, there can be no strangers. Why can't there be strangers? In fact, it is said in Metaphysics that if there are living people, ghosts will not go in when they hear the sound, and it is because some people will see ghosts when they are "low-flame" (that is, unlucky).
