It is unlucky to forget to look at the calendar.

Common methods to get rid of evil spirits:

1. Bagua Palm or Door God hangs at the gate;

2. There is an abacus hanging at the door of the bedroom;

3. Put peach branches under the bed;

4. Old people and children wear red belts (young people don't care, Yang is enough);

5. Old people and children bring peach swords or pig essence or dog teeth;

6. Please come to the Tathagata or Guanyin room.

The above methods are optional and can be used alone or in combination.
