"Zhang Hua: The Lamp Holder" is an epic biography with the theme of "Knowledge Protects Civilization". It gives a panoramic view of the ups and downs of Zhang Hua (232-300), a great master of the Western Jin Dynasty, from a poor student to an empire. The work uses the compilation of "Natural History" as the longitude and the Rebellion of the Eight Kings as the weft. It depicts how he relied on his profound knowledge to learn from Ruan Ji, assisted Emperor Wu in realizing the rule of Taikang, and used the sobriety of "Wren Fu" to guard the cultural fire in the political storm. Through the five parts of "Stargazing in a Poor Family", "Candle Shadow in Luoyang", "Guangling Jue Xian", "Remaining Warmth in the Ashes" and "Spark Inheritance", the book reveals how this encyclopedic scholar broke the barriers of knowledge in an era of strict family relationships, and how his works influenced Ge Hong, Guo Pu and the civilization of the Tang and Song Dynasties through the flames of war. In the end, the image of "Lamp Holder" is sublimated, showing that although individual lives are crushed by the winch of the times, the light of reason they ignite eventually becomes a galaxy that illuminates thousands of years.
