The process of crafting the main ridge beam of a house.
Refers to the process of crafting the main ridge beam of a house (typically the most important beam located at the center of the roof). This involves processing, planing, and carving selected timber to meet the required specifications and ritual standards. Traditionally, the source of the wood and the timing of the work are carefully considered, as this beam is believed to influence the fortune of the entire house. Consequently, its construction time is sometimes chosen based on auspicious dates.
