Where can I buy a good official script copybook?

I don't know if you mean hard pen or soft pen, but I think soft pen calligraphy is still practicing official script. True cursive script and regular script are the foundation. Official script includes regular script and elegant running script, which is a very neat and beautiful font and also shows great skill. As for copybooks, they are generally available in bookstores, and hard-pen calligraphy can also be used to practice official scripts.

Provide your reference. I hope it helps you.

A gentleman makes friends by writing, but by hiding. Help others with friends, and increase wisdom with friends. There is no distinction between old and young in life. Why should we get along first? Friends are not expensive, one person can win a hundred people; No matter how long you have friends, one day, it can be compared to eternity; A friend who doesn't choose the right time can get a fate and benefit for life.

The picture shows my calligraphy and official script. The writing was so ordinary that I smiled. For your reference.
