Why don't you teach us?
My personal recommendation is to train under Aikido, or if you
know anyone who is willing to teach you Taiji Tuishou. This is with
the assumption that most of us are usually in office wear, this
makes kicking or arts that requires high flexibility as a
whole difficult to execute. As Aikido and Taiji Tuishou emphasize
on hand techniques and body positioning (hence need not kick until
your pants split!). And given our harsh laws, Aikido and Taiji
Tuishou should be enough to put down aggressors and not lethally
injuring them.
However, if you're already exposed and experienced to certain
martial arts training, that should give you sufficient
self-confidence when run into situation. If you lack of such
self-confidence, then time to ask yourself why you don't have.
Or you can consider google for some self-defence tips.
3 principles in
self-defence
1) Anticipation and situation awareness
Should be aware of places where possible violence may occur.
Unless necessary, try avoiding these places. However, if you're
there, just be more aware of what's happening around you. Maybe
there is a heated argument that may escalate to a brawling,
etc.
2) Walk-away
Common sense here, if you see something not right, try to move
yourself away from the immediate area. However, if you're caught in
the situation of a heated argument, try to talk your way out.
Remember, the other party may have lost control, but you have to
keep cool, it's your safety we're talking about!
3) Self-defence
When you are unable to walk-away and the argument has escalated
to a fight, then it's time to defend! Try looking out for doors,
corridors where they can facilitate your escape. Remember you're
doing self-defence, not into sparring competition, so staying long
in a fight shouldn't be in any of your options. Techniques should
be either restraining your aggressor or repel their assaults.
Shouting for help, running away should be within your
options.
Declare, this is in no way encouraging anyone to get involved in
any fight. To the best of your ability, avoid violence at all
times! Make love not war!
