Huangdi Yinfu Jing is a seminal Daoist classic. Comprising just over three hundred words, it encapsulates principles of cosmic movement and the mutual responsiveness of yin and yang. The term yinfu refers to cryptic codes of Heaven’s secrets that cannot be spoken outright. According to tradition, the text was discovered by the Tang Daoist Li Quan and carved upon a cliff. Though its actual date of composition remains uncertain, it is believed to be a later work attributed to the Yellow Emperor.
Because of its concise length and rigorous structure, the Huangdi Yinfu Jing has long been regarded as an essential text for practicing regular script. Like other canonical writings, its thought and form embody order and discipline, making it a vehicle for both cultivating the mind and refining brushwork. Through such practice, a writer could nurture his spirit as well as refine his techniques.
This work presents over one hundred characters laid out with balance and optimal structure, inviting viewers to visualise the artist’s execution. The piece is distinguished by elegance and clarity: structures are precise with fluidity and the brushstrokes are structured with immensity. It achieves a subtle fusion of the disciplined laws of regular script with the wisdom of the Huangdi Yinfu Jing, conveying a refined and reserved aesthetic realm.

An intriguing detail appears in the fifth vertical column, where two spaces remain conspicuously blank. In the original text, both should contain the character dao (theft). One may surmise that PU Tzu, for reasons unknown, skipped over them during writing with the intention of returning later. Though the artist’s exact motive can no longer be determined, this omission functions like a behind-the-scenes glimpse into his creative process, endowing the work with a rare immediacy and authenticity—qualities that heighten its significance as a masterpiece.
