It is best to copy with that kind of calligraphy paper, that is, there are lines without columns, and writing with black pen is more classical. If you have a good knowledge of calligraphy and don't feel extravagant, you can try to use the special paper for calligraphy competition, which is available in some calligraphy and painting shops, around 5 yuan 15-20.
You can also use rice paper and copy it in small print, but do you need it? Do not compete. . .
