Twelve pieces are more than a dozen pieces of paper, which are quantifiers from the west. In the past, there was no machine-made paper or paper cutter, but all paper was made by hand, such as Xuan paper, Dongchang paper, running paper and wool paper. About a hundred sheets are folded into three or four stacks to form a stack, and this stack is a knife, and ten stacks are one, packed in a bamboo basket. The number of thick and thin knives varies, but each stack of Zhang Anshi is the same for the same kind of paper. There are two kinds of paper cutters. One is a straight knife with two handles, which can cut four or five sheets of paper at a time. On the paper-cutting case (the case is about 35 cm high and covers an area of a double bed), the papers are flattened one by one and arranged neatly, and there are also "cutting (read cai3) squares" (the cross section of hardwood is about 10*6 cm, and there are various cutting methods. The other is a machete, with a radian of about 220 degrees and a diameter of about 45 cm. It is used to cut a small amount of paper, such as cutting dozens of pieces of paper, folding them in half, placing them on the desktop, putting the machete in the compromise, holding the folding opening with the left hand and holding it with the right hand, and pulling the machete into your arms to cut paper. In this way, how many sheets can the average person cut at a time, which is about 100. Used to keep it secret, used to say 100.
