Ancient Chinese Spy Networks: The Secret Codes of the Southern Song 翠微北征录

What can a 13th-century Chinese military text teach us about modern intelligence and cybersecurity? This documentary-style episode explores Huayue 华岳’s Cuiwei Bei Zheng Lu 翠微北征录, a forgotten Southern Song 兵书 (military treatise) that outlined detailed methods of espionage, secrecy, and coded communication. Based on historian Ma Yejie 马业杰’s 2024 research, we unpack how Huayue designed spy networks (间谍情报网 jiàndié qíngbào wǎng), developed laws of secrecy (保密之法 bǎomì zhī fǎ), and crafted cipher-like systems for transmitting messages (名递法 míng dì fǎ and 数递法 shù dì fǎ). We then connect these ideas to today’s AI-driven intelligence world — from adaptive encryption to space data networks — and ask what ancient ethics can teach about digital truth. A fascinating journey from medieval battlefields to future cyberspace.

Please note that the image of Richard Sorge has been used because, arguably, he was one of the world's most courageous and successful spies, a spy that Huayue 华岳 would trully admire.
