Why do houses have beams?

Liang Shang is here to celebrate. In rural areas, the upper beam, also known as Liang Qing beam, refers to the process of installing the highest middle beam on the roof when building a house. In my hometown, I put a string of firecrackers on the beam, while craftsmen used firecrackers to carry the beam and climb the ladder. This is called "lifting the beam". There should be apricot yellow flags and red paper banners on the beams, among which the most common ones are "Jiang Taigong is here, the gods abdicate" or "Good luck on the beams" and "Good luck shines high", and red cloth should be hung on the beams to celebrate.

According to historical records, capping beams, as a kind of etiquette, began in the Tang and Song Dynasties and spread all over the country in the Ming and Qing Dynasties. The ceremony of offering sacrifices to the beam in Changwu area is still widely circulated and very grand. Before the 1980s, "roof beams" were all made of logs, and then ordinary houses were poured with cement and steel bars. 2 1 century With the advancement of urban-rural integration, fewer and fewer people build houses in rural areas, and the ceremony of putting the beam on the beam has gradually faded out of people's sight.

The custom of Shangliang:

After placing the main girder smoothly, the owner should move the "five-grain colored bag" sent by relatives and friends to the roof and put it in the middle of the beam, which means that the five grains are abundant. In some places, red cloth bags filled with red dates, peanuts, rice, wheat and evergreen are hung in the middle of the main beam, which means "happiness, luck, longevity, happiness and everlasting". After that, the craftsman wrapped the fruit and food in red cloth and threw them into the laundry basket held by the owner in both hands. This process is called "receiving the package", which means catching the treasure.
