If you haven't learned it before, you can start with the most popular tablet in Jiuchenggong. Tian Yingzhang has a basic course of regular script in Ou Yangxun, which is Jiucheng Palace Monument. There is also a set of calligraphy proficiency test training materials: Ou Yangxun's "Jiucheng Palace Monument" is not as exquisite as that, and many people bought it.
In addition, beginners can choose to restore the original stone flower, and Hunan Fine Arts Publishing House can consider the new version.
I hope I can help you and review for me!
