In order to comply with good luck and find a good climate for decoration, ordinary people will make textual research on the start date of decoration, and then decide which day to choose. Many families choose two days as auspicious days for construction. In some places, influenced by traditional customs, fireworks, incense paper and other ceremonies will be held.

Before starting construction, everyone needs to pay attention to the choice of auspicious days in the zodiac. Generally speaking, auspicious days for public buildings and decorations can be found in the old zodiac calendar. Everyone should choose an auspicious day that suits him according to his birthday. We should pay attention to choosing a good groundbreaking day and a bad groundbreaking day. Before the renovation, some surveys should be conducted to see if the relatives of the construction workers are also mourning or if their wives are pregnant. If so, it is forbidden to participate in the construction. And for girls, especially pregnant people, don't participate in the decoration.
