If it is a small town in the north, remember to give a red envelope and have a small note on the seating arrangement, otherwise there will be no place to sit at the opening ceremony. Speaking of Xixiang, I can only roughly explain: Take a house with a south gate as an example, the north side of the table, that is, the side facing the door, is above and the opposite side is below. The top is right-leaning, and the people sitting on it are basically respected people or elders. As for the left and right, it doesn't matter, but one thing, if there are guests at a table, try not to sit at that table. The innermost table in the hall is Supreme, which is the table where my uncle sat when I got married. Similarly, if the table is placed outside, the top is in the same direction as the room.
