Yes, regular calligraphy is a standard practice. It depends on what purpose you use it for: if you practice calligraphy for the convenience of work, then practice with fountain pens and ballpoint pens. There are many copybooks of modern celebrities on the market: Tian Chengzhang, Ma Yan, Pang Zhonghua... If you are interested in the art of calligraphy, you must start with the calligraphy fonts in famous calligraphy books. You must be rigorous in learning from the beginning. If you want to practice calligraphy, you have to persevere. Start with the most basic strokes on the copybook and don’t give up halfway. Each font has its own uniqueness. I like regular script. Another style requires practicing with a pen.
