This book tells of the little-known "Old Tea Road" between China and Russia via Mongolia. This commercial route that opened as a result of China's flourishing tea trade can be traced back to 450 years ago. It reached its zenith in the 18th and 19th centuries, with Sino-foreign cultural exchanges in the hinterland of the Eurasian Continent. This book gives a vivid description of the rise and decline of this commercial road, and changes in the surrounding cultural environment.
