How many kinds of knives, forks and spoons do you put when eating western food? What is the difference?

There are six kinds of knives, forks and spoons when eating western food, as follows:

First, this is what it looked like before eating. Spoons and forks are on the left, forks and spoons are on the right.

Second, put the knife and fork in a cross to show that you are waiting for a second order.

Third, put the fork on the lower left and the knife on the lower right, which means you haven't finished eating, so don't take it away.

Fourth, knives and forks stand side by side, which means eating well. Please take them away.

Five, the knife and fork are placed horizontally, which means that western food is particularly delicious and well received.

Six, insert the knife in the gap of the fork, and the oblique placement of the two shows that it is not delicious, bad review.
