qin na and shuai/throwing,
we need partners.
yes we may practice with poles or dummy
but a real person is indispensible, so the training time will be dependent on the availability of your training partner.
punches and kicks we may use bags and pads, dummies etc.
again it will be better with a training partner wearing protective gear or holding pads.
as far as importance
some would say qin na may be the beginning and the end of everything.
1 we start with qin na before strikes or throw
2. we may also end with qin na.
so every contact of forearms, or hand/wrist will turn into qin na and counter qin na etc.
long before we see a throw or strike.
my point is that qin na would take up 50% of the time.
timing and positioning etc are very important for qin na
or it is more strigent to make it work, thus more practice.
strikes 10%
throws 40% of the time.
