you can reject clients whose name ends in
.dynamic.hinet.net
.HINET-IP.hinet.net
but that won't stop the noise.
I prefer firewalling them:
$ cat /etc/fw.nosmtp
## hinet.net junk sources
#59.112.0.0 - 59.127.255.255
59.112.0.0/12

61.220.0.0/14

61.228.0.0/14
#111.240.0.0 - 111.255.255.255

#114.32.0.0 - 114.47.255.255

then
smtp="-p tcp --dport 25"
grep -v "^#" /etc/fw.nosmtp | while read _subnet _anything; do
