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. Please forgive me if you don't speak well! Every day, we will share cases of monitoring installation and maintenance or network optimization. Every day is combat! 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
