There has been a lot of talk recently about the China Spy Guide. It is, in fact, both interesting and informative. For those wishing to read it, rather than printing it here, we refer you to http://www.gertzfile.com/ChinaSpyguide.htm
Note that while the document is interesting, and possibly entirely authentic, a former FBI counterintelligence agent, who specialized in China, has noted that the document bears little or no relation to Chinese practice of espionage. Even so, it is worth reading.
