As the saying goes: words must be done, walking is like walking, and grass is like running. Learning regular script well is a shortcut to learn other fonts. The most famous regular script is Yan Gu.
Yan Zhenqing's regular script is correct and robust, and his brushwork is bold and unconstrained. His calligraphy is like a figure. Yan Zhenqing was honest and clean, and remained faithful all his life. His calligraphy is broad, vigorous and impressive, and he is one of the influential calligraphy masters in China's calligraphy history.
Liu Gongquan's calligraphy was very famous in the Tang Dynasty, and there was a saying among the people that "Liu Zi is a thousand dollars". His calligraphy structure is rigorous, meticulous, famous for its thinness, attractive posture, even words, thin and hard, following Wei Bei's resolute trend, smooth and graceful stippling, European style and neat appearance, thus creating a vigorous "Liu Ti" calligraphy, which is unique and is praised as "Yan Gu" by the world. Once said: the heart uses a pen, the heart is regular, and the pen is correct.
Although Liu style is difficult to learn, as long as we stick to the rules and grasp the essence of Liu style, Chinese characters will certainly have character. Soft into Wang Xizhi's running script, there is rigidity in softness!
Interest is the best teacher, and learning calligraphy should be based on interest. As long as you are interested, you are willing to try your best to challenge all difficulties. If you go against your own interests, even if it is easy to learn, you are unwilling to stick to it and it is difficult to make progress. Calligraphy is regular, and laying a good foundation can get twice the result with half the effort.
Of course, the progress I'm talking about can't teach you to practice calligraphy in a month. There is no casual success in this world, and so is calligraphy. When I was a child, my teacher once said to me, "It takes 1000 hours to solve the need of shaking hands,1000 hours to do whatever you want with a pen, and 10000 hours to climb Mount Tai, climb Mount Everest and cross the threshold of calligraphy art hall." The teacher is almost ninety years old this year, and still practices tirelessly every day. This shows that the road to calligraphy is difficult.
Of course, the teacher generation has higher requirements for themselves. As our generation, there is no need to be so serious. We just regard it as a hobby. If you want to make a difference on the road of calligraphy, you must work hard like their generation and have a hard time.
