Cheung Yik - more than one actor ?

Actor ID 669<br>Chang Yi / Cheung Yik<br>The films listed on this page cover seven decades.<br>There are a couple in the 30's, a bunch in the 70s, and a couple into the early 90s.<br><br>Is it possible that this is actually two (or even three) actors' listings combined ?<br><br>I do not know for sure who this actor is. But I have a theory or two.<br><br>Theory #1 is that Chang Yi is a pretty young woman who bears an astonishing resemblance to Polly Kuan. The actress I'm referring to here has appeared in <br>- Challenge Of Death (where the name Chang Yi appears in the credits)<br>- Murder Masters Of Kung Fu (no mention of Chang Yi here !)<br>- and probably in Phoenix The Ninja, as the title character (Could Cheung Yik be Pearl Cheung ?!)<br><br>Theory #2 is that Chang Yi is an older man who is a serious fu fighter.<br><br>Can anyone shed light here ? I notice two of the films mentioned on the Cheung Yik page have names against them.<br><br>
