In the countryside, there is such an exquisite married daughter, whose father or mother needs to buy meat for her birthday, and it is a knife of meat. As for how much meat to cut, there is no clear regulation, but it is very particular and must be cut across the board.
There is an old saying: "When a man reaches sixty-six, he must eat his daughter's flesh"; Her daughter is going to the market to buy a knife of meat for her parents on their 66th birthday. Moreover, what is a one-size-fits-all approach? That's how much it is. We can't say that one knife is missing, or one knife is cut if there is more. Buy as much meat as you want with a knife.
