Hard pen calligraphy is different from writing brush.

Let me talk about my feelings: the hard pen that I contacted first, and the soft pen that I learned later, only after careful study did I find that they were slightly different. First of all, the brush is more difficult to master than the hard pen, but if you can embody the use of the brush on the hard pen, then you will understand that they are one, because the brush characters are much smaller than the brush characters, but the sparrow is small and complete, and every brush character must be explained clearly, so you must understand. But I think a pen is not as easy to write as a brush. I mean the successful works. Brush can cover up the defects of knots by changing the thickness of strokes, but pen can't. Writing a pen well requires a strong foundation. I mentioned closure here. I think knots are the soul of calligraphy. Using a pen is just flesh and blood. Choose a copybook that you like and suits your personality. Only after practice can you be interested. This must be decided by yourself, and you can't let others give it to you.
