As far as I could learn through research, wh-questions in Chinese are formed by keeping the wh phrases "in situ", I mean, the wh part is not fronted (like it is in English, for instance).
Some exceptions would correspond to conjoined wh-questions, like "who did Mary see and Peter visit?".
Assuming that I got it right (and please correct me if I didn't), is there any possible way of asking something like "which picture of himself did he take and she post?" ("he" and "himself" beeing the same person) using a fronted wh phrase in Chinese?
