Do you have any copybooks for practicing block letters?
Recommended hard-pen regular script copybooks: Teacher Tian Yingzhang's "Hard-pen Regular Script Techniques" (I haven't read many other copybooks, so I won't recommend them, just for reference)
If you need Teacher Tian Yingzhang's "Hard-pen Regular Script Techniques" in the portal, please download it from my community.
Recommended calligraphy stickers:
Capital letters: Ouyang Xun's "Jiucheng Palace", Yan Zhenqing's "Duobao Pagoda", (Tian Yunzhang's "One Word of the Day", and watch the video)
Small regular script: Zhong Shaojing's "Ling Fei Jing", Wen Zhengming's "Poem of Falling Flowers" and "Ten Chronicles of the Thatched Cottage"
