Since it's cost-free, why not keep trying?  You (Rich) might make a
mistake in your system administration duties some day.

If you're really concerned, you could always attempt to block Chinese
IP addresses.  Lists of all known Chinese IP addresses are available
(e.g., http://www.wizcrafts.net/chinese-iptables-blocklist.html).
They can never be entirely complete, and the list keeps changing, but
it does help to dramatically reduce the attack noise in log files.
Combine that with fail2ban if you have the spare time.
