I have studied regular script for nearly twenty years and have some opinions. First of all, you must have a suitable pen to write the fine print. Different from the big characters, the small characters are small in strokes and often empty in brushwork, so it is necessary to write gossamer and bold from the wind. I wrote a square cabinet of 1.2 cm, in which the thinnest part is 0.2-0.3 mm and the width is 0.7-0.9mm. It can be seen that you can't write without a qualified pen, especially for beginners with poor writing skills. 10 yuan bought Shanlian lower-case pens in Shenyang, Liaoning Province, or lower-case pens in buildings such as Wengang, Jiangxi Province, and some expensive high-grade lobular rosewood pens often cost more than 100 yuan. At first, you are not familiar with distinguishing the good from the bad of a small pen, which requires experience. Writing a fork may be because the pen is not easy to use, or the ink dipped in it is not strong enough, which will lead to bifurcation. Dipping ink in time can not only make the handwriting clear, but also protect the pen from excessive wear. Also, maybe your writing posture is not standard enough. Finally, generally speaking, the main reason is the poor quality of pens or insufficient ink. I hope your writing ability will continue to improve.
I think at least after you enter the post in block letters-you can better understand calligraphy-brushwork, stroke, stroke, stroke force-you can start the pen in block letters.
Calligraphy is not only a process of learning to write well, but also a process of understanding and expressing the beauty of calligraphy, and it is also a process of improving and perfecting personality.
I suggest you find a calligraphy class-do an introductory study
