How do you say 'Can't do it' in Taiwan?

Answer 1

There are three different ways to say "can" in Chinese.

If you "can" do something that requires a skill you say "hui" pronounced "way". So if you say can't do it in chinese, you would say "bu way"

If you "can" do something that requires permission you would say "ke yi" so if you deny someone permission to do something you would say "bu ke yi"

If you can do something physical you would say "neng", It you can't complete a task that has a physical requirement you would say "bu neng"
