Evaluation and appreciation
What is considered good calligraphy often varies depending on individual preferences. However, there are established traditional rules which cannot be violated. Violation of these rules will render a calligraphic work unable to be considered good calligraphy. Those who repeatedly violate these rules are not considered legitimate calligraphers.[4] Among these rules are:

The characters must be written correctly.[4] A correctly written character is composed in a way that is accepted as correct by legitimate calligraphers. Calligraphic works often use variant Chinese characters, which are deemed correct or incorrect on a case-by-case basis, but in general, more popular variants are more likely to be correct. Correct characters are written in the traditional stroke order and not a modern standard (See Stroke Order per Polity).
The characters must be legible.[4] As calligraphy is the method of writing well, a calligraphic work must be recognizable as script, and furthermore be easily legible to those familiar with the script style, although it may be illegible to those unfamiliar with the script style. For example, many people cannot read cursive, but a calligraphic work in cursive can still be considered good if those familiar with cursive can read it.
The characters must be concise.[4] This is in contrast to Western calligraphy where flourishes are acceptable and often desirable. Good Chinese calligraphy must be unadorned script. It must also be in black ink unless there is a reason to write in other ink.
The characters must fit their context.[4] All reputable calligraphers in China were well educated and well read. In addition to calligraphy, they were skilled in other areas, most likely painting, poetry, music, opera, martial arts, and chess. Therefore, their abundant education contributed to their calligraphy. A calligrapher practicing another calligrapher's characters would always know what the text means, when it was created, and in what circumstances. When they write, their characters' shape and weight agrees with the rhythm of the phrases, especially in less constrained styles such as semi-cursive and cursive. One who does not know the meaning of the characters they write, but vary their shape and weight on a whim, does not produce good calligraphy.
The characters must be aesthetically pleasing.[4] Generally, characters that are written correctly, legibly, concisely, and in the correct context are also aesthetically pleasing to some degree. Characters the violate the above rules are often less aesthetically pleasing.
