The answer is as follows:
The so-called Jianghu-style calligraphy is a kind of self-created calligraphy without any calligraphy foundation, which is also a practical font, but it is not very popular from the perspective of calligraphy. People generally call what is within the habit and conforms to the writing experience of predecessors "calligraphy", and what is outside the dimension and self-created fonts is called "Jianghu style".
Human nature is lazy, and it is difficult for many young people to stick to the post seriously and accumulate it for many years. Therefore, many people begin to practice Jianghu body, which is not as standard as academic body. The practice is simple and does not pay attention to connotation and style, as long as it looks chic at first glance.
Because "Jianghu Style" doesn't need complicated brushwork, hard practice of brushwork, brushwork posture, etc., and it doesn't need to consider the method of putting and releasing rules, etc., its brushwork rules are in line with all the unconstrained human nature (which calligraphers call bad habits), so it is often criticized by calligraphers.
The ancient sages just wanted to restrain the bad habits without restraint, so that "calligraphy has laws". When writing, they endowed it with outstanding cultural connotations such as backbone, straightness, preciseness and charm, without hard practice such as brushwork and gesture.
This made writing an art. Therefore, if you really want to learn calligraphy and love it, you should learn it correctly.
