According to the almanac, when choosing a good day to decorate and smash walls, you need to avoid the first and fifteenth day of the lunar calendar, because these two days are the days when folk worship ancestors. Decorating and smashing walls will destroy the feng shui of the home and may cause family problems. Members' fortunes decline. In addition, you also need to avoid door positions in your home. If the doors are facing each other, it is easy for wealth to leak out.

After choosing a good day, you still need to pay attention to some details. First of all, it is best to smash the wall in the morning, because there is enough sunshine in the morning, which can avoid damaging the wires and other items in the wall when smashing the wall. Secondly, when smashing the wall, you should wear some lucky jewelry, such as jade, crystal, etc., which can increase your wealth and health. Finally, you can play some festive music when smashing the wall, such as "Ji Yang Yang", "Back to Back", etc., which can increase the joy and wealth of the home.

In short, it is very important to choose a good day to decorate the walls of an old house. It can not only avoid damaging the feng shui of the home, but also increase the happiness and wealth of the home.
