At first glance, I don't understand the meaning of this proverb. In fact, this proverb is about the table manners culture summarized by our ancestors. When entertaining guests, don't just put three dishes on the table. When six people eat, don't sit like turtles. Let me introduce it in detail.
"There are no three dishes on the table" literally means that you can't put three dishes on the table when you eat, and it will be considered disrespectful to guests when you entertain them. Because in previous sacrificial ceremonies, people always gave priority to three dishes, such as three dishes and three glasses of wine. In this way, if we only put three dishes on the table when we receive guests at ordinary times, it will represent disrespect for the guests, just like sacrifice. So this morality is not good, so there is a saying that there are no three dishes on the table.
Six people don't sit in the tortoise's seat. In the past, people used to eat at rectangular tables. If six people eat together, like turtles, two people on each side, beginning and end 1 person, it is very embarrassing, and it also means disrespect, because if you look closely, you will find that these people's seats are like turtles. ? In rural areas, people always think that the word turtle is a derogatory term, so this practice is also taboo in rural areas. Of course, there may be some superstitious statements in this second half sentence.
