In Romance of the Three Kingdoms, Huang Quan surrendered once. What does Ziyang's calligraphy mean?

"Ziyang" is Zhu, and "calligraphy" does not refer to people who write big characters, but refers to "Spring and Autumn brushwork". Zhu Zhu's Mirror is a simplified version of Zi Jian, which attaches great importance to the praise and criticism of the spring and autumn brushwork. "Ziyang's calligraphy is not wide", which means that this person is too disloyal, and there will be no good words about him in the history books in the future.
