This study examines the earliest surviving ink writing in China, which is said to be written by Lu Ji in his “Pingfu Tie” (A Consoling Letter) in West-Jin Dynasty. The name of the person mentioned in the letter may be related to Zhang Zhi. Taking this as a starting point, if the interpretation of the text in the case disagrees, there is no solid evidence to prove that it is not Zhang Zhi’s ink.
The previous studies, without exception, are based on the “Cursive Script Pingfu Tie” record from the “Xuanhe Calligraphic Florilegium “volume fourteen —” Lu Ji.” However, there is little discussion about volume eight “Yu Shinan” from the same book, one of the “Copy of Zhang Zhi Pingfu Tie” record, the process of recording, and the reason behind it. Therefore, this study introduces the origin of “Copy of Zhang Zhi Pingfu Tie” in Volume eight, “Yu Shinan” of “Xuanhe Calligraphic Florilegium” as the starting point and explores it in combination with relevant records in the Tang Dynasty literature. The fact that Emperor Taizong of Tang ordered Yu Shinan and others to purchase the ink marks of Zhang Zhi and others in the world and copy them shows the authenticity and value of Yu Shinan’s copying of Zhang Zhi’s “Ping Fu Tie.” Later generations ignored it because people doubted the Eastern Han period when Zhang Zhi lived and whether there was paper for writing. Therefore, the “Pingfu Tie” book was determined to be the ink of Lu Ji in the West-Jin Dynasty, which Zhang Chou (Ming Dynasty) also mentioned in his writings.
Based on the above two points, the author in this thesis put forward the possibility of Zhang Zhi being the author for “Pingfu Tie.”
