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!!
