Is Huang Ziyuan's calligraphy worth learning?

Beginners' handwriting is actually a good model, but with the progress of calligraphy, we should change steadily, add some famous posts, and then master it. If you don't know what copybook is more reliable, I suggest you find this article and see "How to choose a brush copybook for beginners of calligraphy (with the names of 46 classic calligraphy introductory copybooks)". I hope it helps you!
