1. Go home before 7 pm.
2. Don't go out alone at night. Traditional folk customs think that you shouldn't go out alone on the night of Ghost Festival. After the sun goes down, the yang will gradually fade and the yin will increase. Going out alone at night will be harassed by yin. From the safety point of view, after beginning of autumn, the daytime will be shortened, and going out alone at night is likely to encounter various dangers. If you really want to go out at night, you'd better be accompanied to avoid the danger.
