1. Fold the four-foot rice paper vertically from bottom to top.
2. Leave the same width on the vertical left and right sides, and leave the sum of the left and right widths above the edge. That is to say, leave 4 cm on the left and right, and 8 cm on the top. So the core is square after leaving the edge. It is called the "basic core" of the stack.
3. According to the number of words written, calculate the number of squares that the "basic core" should overlap. The total number of stacked cells must be greater than the number of words written. That is, there are enough places to write inscriptions.
4. The number of words in the writing content is ÷2, and then add this number to a square number slightly larger than it, and the added number is the number of rows and columns to be overlapped by the "basic core".
