“Numerous volumes have been written to discuss and introduce the Imperial Palace; each has expressed its strong points of view. However, “The Grand Forbidden City ─ The Imperial Axis” is a book written with an axis of history, culture and architecture, in a language complemented by architectural diagrams. A special publication using diagrams to narrate, and to illustrate the history, culture and architectural art of the Imperial Palace in the Forbidden City excellently in an essay accompanied by pictures is still wanting. This publication can be described as a creative work opening up a fresh outlook.” ──LUO ZHEWEN Head, Experts Group on Historical Buildings, Historical Relics Bureau, Senior Engineer (Professorial Grade)
