Taiwanese Etiquette

i'd like to ask what are some do's and don't in regards to Taiwanese etiquette.

for instance shaking hands in some Asian cultures is a no no; taking off one's shoes before entering an office, house or shop is a must.
touching or pointing at anything with one's feet is considered bad manners or eating with the left hand, for example. 

losing one's temper in public is also a big no no in most Asian countries - just grin & bear the inconvenience - in fact it will deter most people if someone loses their calm.  also criticizing the host country, politics or even monarchy won't get much sympathy for the visitor.

is there anything in particular that differentiates Taiwanese etiquette to most Asian / Western cultures ? 

so what's your advice to a foreigner visiting Taiwan for the first time in terms of etiquette ?

thanks
