Advantages of running letters:

First of all, running script is practical. It is not only a very beautiful calligraphy font, but also a hobby of calligraphy. In the future, you will find that it is easy to be recognized, get high marks, or be recognized by your classmates and colleagues, whether you write in the exam, sign your name or even write a good running script after work. It never rains but it pours.

Secondly, compared with Weibei, the latter is more decorative, so it requires higher techniques. To put it bluntly, strong decoration means that it is not popular. If it is not popular, it means that fewer people learn, copy fewer books, and fewer people agree. Crucially, it is difficult to carve words on Wei Bei with a hard pen. There will be some elements of writing back or describing, which is slow and unrealistic, and I have never seen too many people write Weibei with hard pen.

As for the copybook, I recommend Si Mayan. I have been writing to him for seven or eight years. The font is beautiful, much better than Pang Zhonghua.

Some humble opinions, I hope to help you.
