1. Copy the copybooks of some calligraphers (such as Pang Zhonghua) for about a month. At this stage, I am practicing strokes and using a pen;
2. Look at the copybook and write it yourself for about a month. At this stage, I am practicing fonts;
3. The next step is to write and create fonts by yourself, which will take about one month.
After three months, you can make small achievements in calligraphy. Of course, if you want to be a calligrapher, you need to practice and explore persistently.
You can try to practice running script after regular script is small, because running script is actually a combination of regular script and cursive script.
