I recently saw a lot of my friends share a video in facebook on how to defend and protect yourself from sexual abuse.
Although the explanation is in Mandarin, but you can easily understand without listening.
Because it show and teach you step by step on how to protect and defend yourself in several conditions, such as in front, side, from back and so on.
This video is short and about 3 minutes and 13 seconds.
But it’s simple, useful and informative.
I would recommend you to share this page to your friends, especially female friends.
