What does a flowing mat mean?

Running seat is the name of the banquet.

After eating a dish, a dish is flowing, so it is called a "flowing mat". At first, it was named because the floating wooden strips on the canal were convenient for pilgrims to eat.

The wedding banquet is different from the hotel wedding banquet in the city. Hotel wedding banquets usually start after all the guests arrive, but the guests at the wedding banquet are also in a running state. Generally, the time to attend a wedding banquet is determined according to the relatives of the guests.
