The book of my photographs of surviving buildings from China's former Treaty Ports was released in Hong Kong in April 2020. And from 17 July 2024, there is a Traditional Chinese edition. This is available in Hong Kong from The Commercial Press and affiliated stores, and also on TaoBoa.
Except for a new Foreword written by a Hong Kong historian, the contents are the same as the English edition and include 850 images, maps, and an historical summary of each Port.
