"Just because we have won victory, we must never relax our vigilance against the frenzied plots for revenge by the imperialists and their running dogs. Whoever relaxes vigilance will disarm himself politically and land himself in a passive position."
"Address to the Preparatory Committee of the New Political Consultative Conference" (June 15, 1949), Selected Works, Vol. IV, p. 407.
The CJ community may be spread out around the world, but it's strong and growing.
The de facto place all CJ owners go is the The Chang Jiang Experience Yahoo board. That board has a ton of members, a ton of information, and is a lot of fun. Sometimes, though, it devolves into pissing contests between those who like their CJs pure and authentic and those who prefer modern CJs or older CJs with more modern parts/accessories.
If you've got a mechanical question, and want to avoid potential politics, there is a great, but much smaller message board CJ Mechanical Help that you can join.
If you're looking to find others with CJs, check out Chang Jiang Unlimited's Chang Jiang Unlimited Registry. And don't forget to wander around Chang Jiang Unlimited, you can spend weeks lost in all the info on that site.
