Weng Fanggang's calligraphy in running script, executed on a fan leaf in ink and paper, exemplifies the literati tradition of Chinese brush painting during the Qing Dynasty. The running script style, known as xingshu, demonstrates fluid and expressive brushwork that balances spontaneity with technical control, characteristic of Weng's mastery as both a scholar and accomplished calligrapher. This intimate format on a fan leaf reflects the scholar's practice of creating portable artworks for personal enjoyment and exchange among the educated elite.
