zhcon has just moved to http://zhcon.sf.net
In the past few months the gnuchina.org domain stopped to work. As a
result zhcon.gnuchina.org can not be resolved. Moreover, I was
informed that the gnuchina.org web server may no longer be available on
the net for lacking financial support. What a pity it is.
So, the official site of zhcon has moved back to zhcon.sf.net.
