unused port blocking

Every 15 minutes since Friday NIS2010 has blocked 221.192.199.34 from hacking into my computer.

Do I need to be concerned that eventually this hacker will find a way to get past NIS2010?

I traced this IP address to chinaunicom.cn

I'm afraid that if I send a complaint to cchinaunicom.cn  then I will just get on a spam list.
