actually they attempt to pronounce better than us, but
fail.
how many of us can say "three" instead of "tree"?
but the PRCs go "sree" or "se-ree".
how many of us can say "i think" instead of "i ting"?
but the PRCs go "i sink" (with emphasis on k).
how many of us can say "constant?" istead of "constan"?
but the PRCs go "kong-stan-t" (heavy t, too heavy).
and etc.
