Paper: Go to a large-scale cultural and sports supermarket to buy some special hard-pen calligraphy paper, and choose the shape and strokes you are good at.
content: decide the length of the content according to your own specialties. Generally, write some ancient poems and classic classical Chinese articles, and you can enhance your overall effect without punctuation.
finally: count the number of words, without punctuation, and leave half a line for signature. Write!
