you may use several za from both of your hands in turn.

the first one will invite a defense

you then turn around your hand to grab

if no time, forget about grabbing the opponent's defending forearm

just deliver another za one after another

keep going

3 to 6 in a row

and keep going

till you land one.

since your fist coming out from behind your first/front hand

both of your hands stay in your centerline

you are covering your chest/abdomen all the time.

at least that is the theory and practice from tong bei.

your first za was hurried by the second

your second za was hurried by the third

sometimes they are called strung together cannons

lian zhu pao: linked pearl (pearl string) cannons.
