Is it night or day when Liang invites Lu Ban?

Folk culture is carried out during the day.

In the traditional architecture of China, the beam-loading ceremony is an important link, which indicates that the main structure of the building has been completed. Liang Shangli usually chooses the auspicious day of the ecliptic to pray for the stability of the house and the auspiciousness of the owner. Luban is the founder of the traditional woodworking industry in China, and is honored as "Luban Ye". When building a house, people often pray for the blessing of Lu Ban-ye, hoping that the house will be durable and the family will be harmonious and happy. Inviting Lu Ban to beam refers to praying to Lu Ban Ye for the durability of the house and the harmony and happiness of the family through sacrifice when the house beams.
