Zhang Ji's stippling of official script can be said to be a vigorous and powerful Gu Zhuo, but he has no habit of excessive frustration or even deliberate trembling. His vigorous Gu Zhuo is realized by solid and steady brushwork, which keeps the basic elements of calligraphy art, among which the key is that he comprehends and grasps the core law of the pen used in official script, thus finding a pointillism style with individual color, which is a prominent embodiment of the author's superior understanding.
Besides ending, the contrast effect of ink color change is also a remarkable feature in Zhang Jili's calligraphy practice. In his works, there is often a strong contrast between dark and light ink colors, or the ink color is swollen and dizzy, or the dry pen is looming, the font in the thick part is not lost, and the handwriting in the dry part is still visible, which adds a block effect to the online structure.
Although Zhang Ji is famous for his official script, he is also accomplished in regular script and cursive script. His cursive script, in particular, is concise and interesting, similar to his official script and brings out the best in each other. In addition to calligraphy, he is also good at iron pen, and his calligraphy is pure Han Zong method, especially in strictness. Zhu is free and easy, not stick to one pattern.
In form, Zhang Ji chose more ways of integration and coordination, striving to achieve a style that does not violate the traditional aesthetic standards, but is full of the times and personality through various forms of expression under the unified law. This effort is mainly reflected in his shaping of the glyph structure.
Most of the formal effects in Zhang Ji's works are not his inventions, but the results of his in-depth excavation, careful refining and bold play in traditional calligraphy resources. An accidental effect in predecessors' works, the erosion and destruction in ancient inscriptions, and the unique techniques in other art types have become a new way of expression and even a routine skill after his transformation and borrowing.
