What do you mean six people don't sit in the tortoise?
If six people come to dinner, one can't sit on one side and two on the other.
If you sit like this, you look like a turtle from a distance. This way of arranging seats is called turtle seat.
In the eyes of the ancients, turtles had bad meanings. If people at one table make a turtle cushion, they will be teased by people at another table.
Of course, even if there are not six people, a round table can seat more than six people.
On one side of the round table, several people sit next to each other in clusters, but on the other side, they are far apart. From a distance, they look like turtle seats.
Moral:
The ancients paid great attention to the placement of seats on the dining table. Turtle seat not only means bad things, but also outsiders look as if the table is disunited and unfriendly.
The proverb "six people don't sit on the turtle seat" is still very popular in today's society, because people have many opportunities to attend parties now, but most of them sit on the turtle seat.
A few good friends sat together, around one side of the table, drinking food, while the other side was deserted and eating by themselves.
