As for training, we are doing the things you showed us and I feel as though we are starting to
get better. Like with liu feng si bi i realized that we always start twisted in the torso and if we start not twisted it works much better not great but it is much easier that it is when we are twisted. There was one day about a month ago John and I were pushing hands and we both got this feeling by trying really hard not to move our centre and just moving our hands we were able to push a lot better. My friend would push on us and when we got it it looked the way he reacted was really strange. It was exatly the same as when stopping in the middle of push hands and doing what we were doing to each other to the air would reveal what we were actually doing it looked the same. It was like we just let him do what he was doing.
It did not last that long though because when we tried it on my sister it did not work as well. However it seems that when we are pushing hands we treat the opponent the same way we would treat air, and that is why what I do is pretty much useless.
