There are 100 pieces of rice paper in one knife.
A "knife" of paper, describes the papermaking technique in ancient times. The newly made paper is laid out neatly, without being cut or dyed with any ink. The thick pile of standing blanks was immediately split open, and the burrs did not fly away. The sharp sound was still in my ears. Capturing this feeling, I called the amount that can be completely cut off by "one knife" a "knife". But of course there are no two knives in the world that are equally sharp, let alone a knife operator with the same strength. The results are specious and inconsistent. Let's just calculate and take a sample of the approximate values ??that each can achieve, so the result is different. "Sufficiency" has created this romantic and unrealistic quantifier, commonly known as "knife".
Usually a knife contains 100 pieces of paper, but in ancient times there were also sayings of 25 or 70 pieces.
