Yeah, but given they want people with English as their first language you're likely to end up with applicants majoring in linguistics rather than comparative literature (since fluency in Chinese is required).
It's simply a poorly designed job-ad.
My field of expertise with horrible job-ads is IT. When looking for managers companies often list a number of programming languages and operating environments required for applying. In the end they're stuck with technicians poorly suited to lead people since leadership abilities were a secondary requirement to begin with.
