I am translating a recommendation letter and there is a question. It goes like this:<br/><br/><i>As the principal of Wuhan Foreign Languages School </i><span style="color:#ff0000;"><b>where</b></span><i> Miss Yan is, ...</i><br/><br/>I wonder which is better? <i>where</i> or <i>in which</i> ? Is there any better saying? Thanks.
