What does it mean to seal Longmen in Wenzhou?

Longmen Pass in Wenzhou means: it refers to a funeral custom in Wenzhou.

Longmen:

On the day of the funeral, the eldest grandson led the way with a "bamboo lantern", the nephew carried the portrait, and all relatives lined up with incense. There are drum teams, foreign military bands, percussion classes, waist drum teams, wreaths, flower cards and local funeral teams for the elderly. There are portraits of the dead in the pavilion, and salutes and whips are placed from time to time. When the funeral procession crosses the bridge, the son should bow to show his gratitude.

When the coffin arrived at the cemetery, it was pushed into the tomb pit at the right time and built with bricks. There is only a hole about an inch square in the middle, which is called "Longmen". When the time comes, light a fire, play music, set off a cannon, and the dutiful son falls to the ground. A mason blocked the Longmen with a small brick and sealed it.

After the burial, the band and colorful flags returned with Rongting. The dutiful son is dressed in red cloth, and each person carries a "Feng Shui tree" and a bottle of "Feng Shui", commonly known as "returning to the mountain". At home, the daughter-in-law and daughter-in-law arrange to meet each other in "Xiangting" and "Rongting", commonly known as "Yuanting". Connect nave first, pay and enter the mourning hall.

There is another explanation for the ancient Guanlongmen: it means blocking the main entrance of the imperial examination.
