As for contemporary famous artists, I personally like Qigong and Tian Yingzhang. If you like European style, you can buy Tian Yingzhang's copybooks to practice. I remember reading a book called regular script tutorial before, and the specific method of practicing calligraphy is very detailed. When buying copybooks, it is best to choose video teaching CDs to avoid taking too many detours.
Qigong's words are very individual. The basic characteristics of Tian Yingzhang are similar to those of European style, which is more suitable for people with atmosphere. There are Gu Zhongan, Si Mayan, Zou Mubai, Lu Zhongnan and so on.
It doesn't matter whose copybook you choose, but you must choose a classic and famous one (except Pang Zhonghua). If you are interested in calligraphy, you should get close to the ancients or practice soft writing. If you just want to practice your handwriting well, choose a contemporary master to do it quickly. Those people I listed earlier, you'd better look for their calligraphy works and choose the one you like best.
As for the method, the pen holding posture is correct. Just practice for 30-60 minutes every day. It's no use practicing too much, but you must concentrate for half an hour. Long-term practice of calligraphy is very beneficial to the adjustment of mentality, so don't rush for success. As for the method of pasting, I really don't want to code any more. I'm so tired today. Search on the internet yourself. In fact, good copybook tutorials are all self-contained. From point to surface, carefully study the structure of each word, and how much strength and emotion you have devoted to each stroke. Don't be impetuous, and strive for success. Every word you write must be finished by yourself. Draw a few strokes first, you can master its specific structure, read the post carefully, don't read it one by one, write it from memory after reading it, and then compare your own writing with the post to see if there is any difference.
I wish you success!
