It was my first video when i bought this dummy (from germany). I pratice Nam Hong Son Kungfu, it is not wing tsun. It is a mix from shaolin and vietnamese kungfu. So please dont take it serious what i did there because it is just for hardering my arms and my speed. So that all freestyle,no form or technics from wingtsun. (I learned it from movies like "Ip Man" ) Thanks all for your comment and assessment. :)
