Hello everyone, I am Hainan weak current Xiao Hu Most of the videos are actual combat. I was born in painting and was not a major, so I was very amateur ~ Sometimes there may be differences between sharing your actual combat experience and some standard theories.

Responsible for the installation of monitoring, network, very amateur!! Subscription link: bit.ly/3AYqXwA Like to remember to subscribe ~ #Vlog # Monitoring # Teaching # Hainan Weak Current Xiao Hu
