Ou Yangxun's Qian Zi Wen is a small print. Do you want to write big when copying? Or copy the fine print directly.

The calligraphy of the predecessors should be close to the original size. Bao, a famous calligrapher in Qing Dynasty, once said that "different fonts have different brushstrokes", that is, the brushstrokes of big characters and small characters are different, and no mistakes can be made.

I don't know whether the thousand-character script you are talking about is Ou Yangxun's running script thousand-character script or lower case thousand-character script. The font of his running script is not small, and the running script written by calligraphers is generally much smaller than this. If you want to write something bigger, you can't enlarge it. If you want to write something bigger, there are Chinese copybooks such as Huadu Temple, Yugong Monument, Jiuchenggong Monument and Huangfujun Monument.
