Zhao Ziang didn't talk much about calligraphy, but the most famous sentence was "Calligraphy is based on pen, but it needs labor to finish writing. The word Gaijie has been circulated from time to time, and it is not easy to use a pen through the ages. " Later, this sentence became the motto of people who studied calligraphy, and it was also the core issue of learning calligraphy.
Here, "it is not easy to use a pen through the ages" means that the core problem of calligraphy is its use of a pen. Even though the structure of words will change with the changes of the times, the brushwork will never change. Of course, everyone has a different understanding of calligraphy, so this sentence has other meanings. The key issue of brushwork will not change.

Zhao Ziang made such achievements in calligraphy because he mastered the brushwork of calligraphy. Zhao Ziang is good at the "six scripts", namely, Da Zhuan, Xiao Zhuan, Cao Zhang, Li Shu, regular script, running script and cursive script. It is generally believed that Zhao Ziang's greatest achievement in calligraphy is his cursive script.
This is what he said besides using a pen: "In ancient times, nothing can be taken from today." This means that learning calligraphy should be centered on the ancients, not now.
