This book details the organizational structure, operational experience, and working principles of the underground party at that time. The experience of the underground party's struggle may be far away to today, but the wisdom and power contained in it are still worthy of our study and reference.
The shock brought by this book is not just at the literary level. As a 100-year-old writer who was an eyewitness of the underground struggle at that time, the author experienced the brutal underground struggle half a century ago and looked back on the past in simple language, leaving behind precious historical memories.
