2. Among modern calligraphers, "breaking grass" is the most common. Its characteristics are brushwork and strokes, so that most calligraphers have evolved their own styles since ancient times. Wang Xizhi learned some from his calligraphy style, and took some from Wang Duo's calligraphy posts. Zhu Yunming, Sun and other famous artists learn from each other's strong points and learn from each other. This writing is similar to this grass.
3. "Grass line" is close to cursive script and converges to grass. Zhang Huai's Book Theory in the Tang Dynasty said: Those who are true are called "true", and those who take grass are called "walking grass". So, there is this difference. Zheng Banqiao's good six-and-a-half calligraphy is a font in calligraphy, a "hybrid" with many components. Zheng Banqiao combines seal script, official script and running script in one furnace, with eight points between them, so he calls himself "six-and-a-half-script method".
4. A font between regular script and cursive script can be said to be cursive script or cursive script. It is to make up for the shortcomings of slow writing in regular script and illegible cursive script. The brushwork is not as sloppy as cursive script, and it is not required to be as correct as regular script. There are more methods of mold opening than cursive writing, which is called "mold opening".
For beginners, it is recommended to write a running script. If you take a shortcut, write an official script! Personal advice! I started with the official script of Cao Quanbei!
